We Keep Coding

Importing data to google maps though Asp.net/C#

I build an example and made it run, but the problem is, that it only shows one of the markers instead of them both.
This is what is in my repeater.
12.545020 55.675020 , 12.388520 55.618460
My code looks like this
<asp:Repeater ID="rptMarkers" runat="server">
<ItemTemplate>
<asp:Label ID="lbl_Adresse" CssClass="LongitudeLabel" runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "Longitude")%>' />
<asp:Label ID="Label1" CssClass="LatitudeLabel" runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "Latitude")%>' />
<asp:Label ID="Label2" CssClass="LocationLabel" runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "Adresse")%>' />
<asp:Label ID="lbl_Fornavn" CssClass="Cust_NameLabel" runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "Fornavn")%>' />
<asp:Label ID="lbl_Titel" CssClass="DescriptionLabel" runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "Titel")%>' />
<asp:Label ID="Label3" CssClass="BilledeLabel" runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "Billede")%>' />
<asp:Label ID="Label4" CssClass="IDLabel" runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "BrugerID")%>' />
</ItemTemplate>
,
my javascript look like this
var markers = { locationLatitude: "", locationLongitude: "", Cust_Name: "", Description: "" };
var markerArray = [];
window.onload = function () {
var t = self.setTimeout(function () {
var size = $('.LocationLabel').length;
for (i = 0; i < size; i++) {
var id = $('.IDLabel').eq(i).text();
var Location = $('.LocationLabel').eq(i).text();
var CustName = $('.Cust_NameLabel').eq(i).text();
var Description = $('.DescriptionLabel').eq(i).text();
var Billede = $('.BilledeLabel').eq(i).text();
markers.locationLatitude = $('.LatitudeLabel').eq(i).text();
markers.locationLongitude = $('.LongitudeLabel').eq(i).text();
markers.Cust_Name = CustName;
markers.Description = "Navn: " + CustName + "<br />" + "Titel: " + Description + "<br />" + Billede + "<br />" + 'Se Profil';
markerArray.push(markers);
}
var mapOptions = {
center: new google.maps.LatLng(markers.locationLatitude, markers.locationLongitude),
zoom: 7,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var infoWindow = new google.maps.InfoWindow();
var map = new google.maps.Map(document.getElementById("map"), mapOptions);
for (i = 0; i < markerArray.length; i++) {
var data = markerArray[i]
var myLatlng = new google.maps.LatLng(data.locationLatitude, data.locationLongitude);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: data.Cust_Name
});
(function (marker, data) {
google.maps.event.addListener(marker, "click", function (e) {
infoWindow.setContent(data.Description);
infoWindow.open(map, marker);
});
})(marker, data);
}
});
}
This example works, but it dont show all the markers on the map

DataTable in ViewState is Returning Deleted Rows

I am currently working on a dynamic gridview that will allow a user to add or delete rows in order to be saved as database entries later on.
My gridview markup is as such:
<asp:UpdatePanel ID="upAirporterSchedule" runat="server" ChildrenAsTriggers="true" UpdateMode="Conditional">
<ContentTemplate>
<asp:GridView ID="gvAirporterSchedule" runat="server" ShowFooter="true" AutoGenerateColumns="false" CssClass="table table-striped table-bordered table-hover dataTable no-footer" OnRowDataBound="gvAirporterSchedule_RowDataBound" OnRowCommand="gvAirporterSchedule_RowCommand">
<Columns>
<asp:TemplateField HeaderText="Location" ItemStyle-Width="25%">
<ItemTemplate>
<asp:DropDownList ID="ddlScheduleLoc" runat="server" CssClass="form-control"></asp:DropDownList>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Start Date">
<ItemTemplate>
<div class="input-group">
<asp:TextBox ID="tbxAirporterStartDate" runat="server" CssClass="form-control date-picker" Text='<%# Eval("StartDateColumn") %>'></asp:TextBox>
<span class="input-group-addon">
<i class="fa fa-calendar"></i>
</span>
</div>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="End Date">
<ItemTemplate>
<div class="input-group">
<asp:TextBox ID="tbxAirporterEndDate" runat="server" CssClass="form-control date-picker" Text='<%# Eval("EndDateColumn") %>'></asp:TextBox>
<span class="input-group-addon">
<i class="fa fa-calendar"></i>
</span>
</div>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Departure Time">
<ItemTemplate>
<div class="input-group">
<asp:TextBox ID="tbxAirporterDepTime" runat="server" CssClass="form-control time-picker" Text='<%# Eval("DeptTimeColumn") %>'></asp:TextBox>
<span class="input-group-addon">
<i class="fa fa-clock-o"></i>
</span>
</div>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Duration">
<ItemTemplate>
<asp:TextBox ID="tbxAirporterDuration" runat="server" CssClass="form-control" Text='<%# Eval("DurationColumn") %>'></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Delete">
<ItemTemplate>
<asp:Button ID="btnDel" runat="server" CssClass="btn btn-default" Text="Delete" CommandName="DeleteRow" />
</ItemTemplate>
<FooterStyle HorizontalAlign="Right" />
<FooterTemplate>
<asp:Button ID="btnAdd" runat="server" CssClass="btn btn-default" Text="Add Entry" CommandName="AddRow" />
</FooterTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
</ContentTemplate>
</asp:UpdatePanel>
Aside from this grid, I have some other fields in the user control. When I go to save, the user will click a button at the bottom of the user control which will package up the form fields above it and the grid into some classes and shoot this off to the database code to add/update this data.
Page.Validate("AirporterFares");
if (Page.IsValid)
{
try
{
// Save trip information.
SysVarService.SharedRideTrip trip = new SysVarService.SharedRideTrip();
if (_tripID > 0)
trip = Global.sysVarService.GetSharedRideTripByID(_tripID);
trip.isVisible = 1;
trip.productType = ReservationService.ProductType.TOUR;
trip.originStopID = Convert.ToInt32(ddlOrigin.SelectedValue.ToString());
trip.destinationStopID = Convert.ToInt32(ddlDestination.SelectedValue.ToString());
trip.defaultDuration = 0;
trip.effectiveDate = DateTime.Parse(tbxAirporterEffDate.Text.Trim());
trip.startTimeOfDay = new DateTime(trip.effectiveDate.Year, trip.effectiveDate.Month, trip.effectiveDate.Day, 1, 1, 1);
trip.endTimeOfDay = new DateTime(trip.effectiveDate.Year, trip.effectiveDate.Month, trip.effectiveDate.Day, 1, 1, 1);
// Save the two fare information.
SysVarService.SharedRideTrip_ShuttleFare aFare = new SysVarService.SharedRideTrip_ShuttleFare()
{
effectiveDate = trip.effectiveDate,
effectiveTravelDate = trip.effectiveDate,
paxTypeID = 1,
oneWayCost = Foundation.StringFormatter.currencyToDouble(tbxAirporterAdultFare.Text.Trim()),
returnCost = 0.00,
numPax = 1,
Currency = 0
};
SysVarService.SharedRideTrip_ShuttleFare cFare = new SysVarService.SharedRideTrip_ShuttleFare()
{
effectiveDate = trip.effectiveDate,
effectiveTravelDate = trip.effectiveDate,
paxTypeID = 2,
oneWayCost = Foundation.StringFormatter.currencyToDouble(tbxAirporterChildFare.Text.Trim()),
returnCost = 0.00,
numPax = 1,
Currency = 0
};
string status = "";
if (_updating)
status = Global.sysVarService.UpdateAirporterFare(trip, aFare, cFare, GetScheduleEntries());
else
status = Global.sysVarService.AddAirporterFare(trip, aFare, cFare, GetScheduleEntries());
if (!String.IsNullOrEmpty(status))
{
spanErrorMsg.Visible = true;
spanErrorMsg.InnerText = status;
return;
}
}
catch (Exception ex)
{
spanErrorMsg.Visible = true;
spanErrorMsg.InnerText = ex.ToString();
return;
}
Response.Redirect("~/Internal/Admin/Default.aspx?action=Airporter_Fares");
}
When I go to either add or update, I call GetScheduledEntries, which is supposed to loop through the datatable (grabbing it from the viewstate) and convert the templated fields into object properties and stuff these objects in a list.
private List<AdminConfigService.SharedRideTimes> GetScheduleEntries()
{
int idx = 0;
List<AdminConfigService.SharedRideTimes> schedule = new List<AdminConfigService.SharedRideTimes>();
if (gvAirporterSchedule.Rows.Count >= 1)
{
for (int i = 1; i <= gvAirporterSchedule.Rows.Count; ++i)
{
// Get data controls.
DropDownList ddl = (DropDownList)gvAirporterSchedule.Rows[idx].Cells[0].FindControl("ddlScheduleLoc");
TextBox startDate = (TextBox)gvAirporterSchedule.Rows[idx].Cells[1].FindControl("tbxAirporterStartDate");
TextBox endDate = (TextBox)gvAirporterSchedule.Rows[idx].Cells[2].FindControl("tbxAirporterEndDate");
TextBox deptTime = (TextBox)gvAirporterSchedule.Rows[idx].Cells[3].FindControl("tbxAirporterDepTime");
TextBox duration = (TextBox)gvAirporterSchedule.Rows[idx].Cells[4].FindControl("tbxAirporterDuration");
schedule.Add(new AdminConfigService.SharedRideTimes()
{
StartDate = DateTime.Parse(startDate.Text.Trim()),
EndDate = DateTime.Parse(endDate.Text.Trim()),
DepartureTime = DateTime.Parse(deptTime.Text.Trim()),
Duration = Convert.ToInt32(duration.Text.Trim()),
EffectiveDates = "",
StopID = Convert.ToInt32(ddl.SelectedValue.ToString())
});
idx++;
}
return schedule;
}
else
return schedule;
}
The problem is, if I delete rows from this grid view and then attempt to save the form, the datatable from the viewstate is bringing back those deleted rows and acting like they are still existing for saving, even though the gridview and the datatable do not have that row anymore (when the DeleteRow command goes through).
else if (e.CommandName == "DeleteRow")
{
SetRowData();
if (ViewState["AirporterScheduleTable"] != null)
{
DataTable dt = (DataTable)ViewState["AirporterScheduleTable"];
DataRow currentRow = null;
GridViewRow gvr = (GridViewRow)(((Button)e.CommandSource).NamingContainer);
int idx = gvr.RowIndex;
if (dt.Rows.Count > 1)
{
dt.Rows.Remove(dt.Rows[idx]);
currentRow = dt.NewRow();
ViewState["AirporterScheduleTable"] = dt;
gvAirporterSchedule.DataSource = dt;
gvAirporterSchedule.DataBind();
SetPreviousData();
}
}
}
private void SetPreviousData()
{
int idx = 0;
if (ViewState["AirporterScheduleTable"] != null)
{
DataTable dt = (DataTable)ViewState["AirporterScheduleTable"];
if (dt.Rows.Count > 0)
{
for (int i = 0; i < dt.Rows.Count; ++i)
{
// Get data controls.
DropDownList ddl = (DropDownList)gvAirporterSchedule.Rows[idx].Cells[0].FindControl("ddlScheduleLoc");
TextBox startDate = (TextBox)gvAirporterSchedule.Rows[idx].Cells[1].FindControl("tbxAirporterStartDate");

TextBox deptTime = (TextBox)gvAirporterSchedule.Rows[idx].Cells[3].FindControl("tbxAirporterDepTime");

ddl.SelectedValue = dt.Rows[i]["LocColumn"].ToString();
startDate.Text = dt.Rows[i]["StartDateColumn"].ToString();
endDate.Text = dt.Rows[i]["EndDateColumn"].ToString();
deptTime.Text = dt.Rows[i]["DeptTimeColumn"].ToString();
duration.Text = dt.Rows[i]["DurationColumn"].ToString();
idx++;
}
}
}
}
private void SetRowData()
{
int idx = 0;
if (ViewState["AirporterScheduleTable"] != null)
{
DataTable current = (DataTable)ViewState["AirporterScheduleTable"];
DataRow currentRow = null;
if (current.Rows.Count > 0)
{
for (int i = 1; i <= current.Rows.Count; ++i)
{
// Get data controls.
DropDownList ddl = (DropDownList)gvAirporterSchedule.Rows[idx].Cells[0].FindControl("ddlScheduleLoc");

TextBox deptTime = (TextBox)gvAirporterSchedule.Rows[idx].Cells[3].FindControl("tbxAirporterDepTime");
TextBox duration = (TextBox)gvAirporterSchedule.Rows[idx].Cells[4].FindControl("tbxAirporterDuration");
currentRow = current.NewRow();
current.Rows[i - 1]["LocColumn"] = ddl.SelectedValue;
current.Rows[i - 1]["StartDateColumn"] = startDate.Text;
current.Rows[i - 1]["EndDateColumn"] = endDate.Text;
current.Rows[i - 1]["DeptTimeColumn"] = deptTime.Text;
current.Rows[i - 1]["DurationColumn"] = duration.Text;
idx++;
}
ViewState["AirporterScheduleTable"] = current;
}
}
}
There doesn't seem to be any where in the code that I am not updating the ViewState datatable when I either delete or add entries to this dynamic gridview. What could be causing the difference in ViewStates? Does the full postback of the button outside of the UpdatePanel and GridView have a different ViewState?
I also pretty much followed this tutorial exactly.

Turned out to be one of those cases where you overlook something simple. When I was populating the grid with data on load, I did not protect it with a
if (!Page.IsPostback)
Because of that, every time the row was deleted, it would refill the data table with the data on Page Load and cause the weird issues where deleted rows didn't seem to be getting deleted.

load codebehind Gridview dynamically

I am generating this tags (IT,Marketing....) dynamically(codebehind) from the sql using linq to sql.
And when you click on any of the the tabs it will show the gridview as per table created in database.
But the gridview binding is done during page_load event, so everything is generated during page_load, now when you click any of the blue tabs , it will show you pre-generated gridviews.
Now i want to generate or load gridviews when i clck on [+] sign of any of the tabs and not during the page load
<form id="form1" runat="server">

banckend code:

//ddl_db.Items.Add(new ListItem(person.NAME_FIRST));
}

}

If you use a Multiview control for your tab container then you should be able to bind your code to load the Gridview to the ActiveViewChanged event and change your ActiveViewIndex property for that Multiview when your users navigate between your tabs.

Insert <p> tags with C#?

This is sort of a weird question, but is there a way to insert <p> tags around some imported text? I have a list of blog entries, each of which comes from its own source (I think it's a copy-paste job into Sitecore). All entries have an "Introduction" which is the blurb about the article. Some of these has <p> tags enclosing them and others do not (I'm not sure why and I can't change the source material--I can only have control on how it looks when it comes into the blog listing page) I'm thinking there should be a check to see if they do exist first, although I am not sure how that could be done.
This is the front end for the blog listing:

You can always do something like...
dr["Introduction"] = BlogEntry.Fields["Introduction"].Value
.Replace("\n\n", "</p><p>");
... or whichever escape characters are being used to denote separation of paragraphs in your source data. Alternatively, you could use Regex utilities. See Example 3 in this article for further reference.

Firstly in your GridView you've got
OnItemDataBound="EntryDataBound"
OnItemDataBound isn't an event of GridView I'm a little surprised that works!
Use
OnRowDataBound="EntryList_RowDataBound"
This is my common pattern for GridView's and Repeaters, noticed I've used a Literal control in the HTML, I'm not a mega fan of Eval! Also note that if (dataItem == null) just if there's a data item for that row, RowTypes like header and footer don't have any data, it's easier than the typical if(e.Row.RowType == DataControlRowType.Header) etc

{
var dataItem = e.Row.DataItem as EntryItem;
if (dataItem == null)
return;
var imageControl = e.Row.FindControl("EntryImage") as global::Sitecore.Web.UI.WebControls.Image;
var introductionControl = e.Row.FindControl("IntroductionLiteral") as Literal;
if (imageControl == null || introduction == null)
return;
imageControl.MaxWidth = m_imageMaxSize.Width;
imageControl.MaxHeight = m_imageMaxSize.Height;
if (dataItem.ThumbnailImage.MediaItem == null)
imageControl.Field = "Image";
if (!string.IsNullOrEmpty(data["introduction"]))
introductionControl.Text = string.Format("<p>{0}</p>", data["introduction"].ToString().Replace("\n\r", "</p><p>"));
}
Also if you've got a list of Sitecore objects why don't you just bind that to the GridView, then in your RowDataBound method get the item back
var dataItem = e.Row.DataItem as Item;
and then do the logic in the BindEntries method in there, would prob be cleaner code and you wouldn't have to use stupid DataSets! Just an idea.

How to transfer item from one datalist to other datalist?

I have a datalist
<asp:DataList ID="dlstImage" runat="server" RepeatDirection="Horizontal" RepeatColumns="5"
CellSpacing="8">
<ItemTemplate>
<asp:ImageButton ID="Image" runat="server" ImageUrl='<%#"~/Controls/ShowImage.ashx?FileName=" +DataBinder.Eval(Container.DataItem, "FilePath") %>'
OnCommand="Select_Command" CommandArgument='<%# Eval("Id").ToString() +";"+Eval("FilePath")+";"+Eval("Index") %>' /><br />
<asp:Label ID="lbl" runat="server" Text="Figure"></asp:Label><%# dlstImage.Items.Count + 1%>
</ItemTemplate>
</asp:DataList>
In which i am binding the image after uploading through uplodify upload, now i have one more datalist
and two btn up and down,
<asp:ImageButton ID="ibtnMoveUp" runat="server" ImageUrl="~/App_Themes/Default/Images/moveup.bmp"
Style="height: 16px" ToolTip="MoveUp The Item" />
<asp:ImageButton ID="ibtnMoveDown" runat="server" ImageUrl="~/App_Themes/Default/Images/movedown.bmp"
ToolTip="MoveDown The Item" />
<asp:DataList ID="dlstSelectedImages" runat="server" RepeatDirection="Horizontal"
RepeatColumns="5" CellSpacing="8">
<ItemTemplate>
<asp:ImageButton ID="Image" runat="server" /><br />
<asp:Label ID="lbl" runat="server" Text="Figure"></asp:Label><%# dlstImage.Items.Count + 1%>
</ItemTemplate>
</asp:DataList>
My both datalist is in the same webuser control, datalist1 and datalist2 and I have 2 btn up and down, when i select one image from datalist1 and click on down btn then the selected image should move to datalist2. How to do that? someone please help me,

You need to handle the ItemCommand event of one DataList in which you have to copy the selected data (image) into another dataSource of two DataList and remove that item from the datasource of one DataList.
Markup:
<asp:DataList
ID="DataList1"
runat="server"
OnItemCommand="PerformMove"
>
<ItemTemplate>
<br /><%#Eval("Text") %>
<asp:Button ID="btn1"
runat="server"
Text="Move"
CommandName="cmd"
CommandArgument='<%#Eval("Text") %>'
/>
</ItemTemplate>
</asp:DataList>
<asp:DataList ID="DataList2" runat="server">
<ItemTemplate>
<br /><%#Eval("Text") %>
</ItemTemplate>
</asp:DataList>

DataList2.DataBind();
}
}

{
if (e.CommandName == "cmd")
{
List<Data> list1 = Session["list1"] as List<Data>;
List<Data> list2 = Session["list2"] as List<Data>;
list1.Remove(new Data() { Text=e.CommandArgument.ToString() });

DataList1.DataSource = Session["list1"];
DataList1.DataBind();
DataList2.DataSource = Session["list2"];
DataList2.DataBind();
}
}

I am using this code and its working well for me.
ArrayList ImgArry = new ArrayList();
path = objGetBaseCase.GetImages(TotImgIds);
ImgArry.Add(SelImgId);
ImgArry.Add(SelImgpath);//image name
ImgArry.Add(SelImgName);//image path
//path.Remove(ImgArry);
List<ArrayList> t = new List<ArrayList>();
if (newpath.Count > 0)
t = newpath;
t.Add(ImgArry);
newpath = t;
for (int i = 0; i < newpath.Count; i++)
{
ArrayList alst = newpath[i];
newtb.Rows.Add(Convert.ToInt32(alst[0]), alst[1].ToString(), alst[2].ToString(), i);
}
dlstSelectedImages.DataSource = newtb;
DataBind();
path = objGetBaseCase.GetImages(TotImgIds);
for (int i = 0; i < path.Count; i++)
{
ArrayList alst = path[i];
tb.Rows.Add(Convert.ToInt32(alst[0]), alst[1].ToString(), alst[2].ToString(), i);
}
dlstImage.DataSource = tb;
DataBind();
