model binding webform TryUpdateModel not Working - c#

I have a simple formview and simple modelbinding in webform:
<asp:FormView ID="frm" ItemType="SabaDoor2.Models.Content" SelectMethod="frm_GetItem" UpdateMethod="frm_UpdateItem" DataKeyNames="Id" runat="server">
<ItemTemplate>
<fieldset>
<legend>
<asp:Label ID="lblName" Text='<%# Item.Name %>' runat="server"></asp:Label>
</legend>
<p>
<label>descripion :</label>
<asp:Label ID="lblDescription" Text='<%# Item.Description %>' runat="server"></asp:Label>
</p>
<p>
<asp:Button ID="btnEdit" Text="edit" CommandName="Edit" runat="server" />
</p>
</fieldset>
</ItemTemplate>
<EditItemTemplate>
<fieldset>
<legend>
<asp:Label ID="lblName" Text='<%# Item.Name %>' runat="server"></asp:Label>
</legend>
<p>
<label>description :</label>
<asp:TextBox ID="txt" Text='<%# Item.Description %>' runat="server" ></asp:TextBox>
</p>
<p>
<asp:Button CommandName="Update" ValidationGroup="mainPropertyGroup" runat="server" ID="btnUpdate" Text="update" />
<asp:Button CommandName="Cancel" ValidationGroup="mainPropertyGroup" runat="server" ID="btnCancel" Text="cancel" />
</p>
</fieldset>
<br />
</EditItemTemplate>
</asp:FormView>
and in code:
Models.Model1Container _db = new Models.Model1Container();
protected void Page_Load(object sender, EventArgs e)
{
bindEvents();
lblResult.ForeColor = System.Drawing.Color.Green;
lblResult.Text = "";
if (!IsPostBack)
{
}
else
{
}
}
private void bindEvents()
{
frm.ItemUpdated += frm_ItemUpdated;
}
void frm_ItemUpdated(object sender, FormViewUpdatedEventArgs e)
{
if (e.Exception == null)
{
lblResult.ForeColor = System.Drawing.Color.Green;
lblResult.Text = "done!";
}
else
{
lblResult.ForeColor = System.Drawing.Color.Red;
lblResult.Text = "error:" + e.Exception.Message;
e.KeepInEditMode = true;
}
}
public SabaDoor2.Models.Content frm_GetItem([System.Web.ModelBinding.QueryString("Id")]int? Id)
{
return _db.Contents.Find(Id);
}
// The id parameter name should match the DataKeyNames value set on the control
public void frm_UpdateItem(int Id)
{
SabaDoor2.Models.Content item = null;
item = _db.Contents.Find(Id);
if (item == null)
{
// The item wasn't found
ModelState.AddModelError("", String.Format("Item with id {0} was not found", Id));
return;
}
var result = TryUpdateModel(item);
if (ModelState.IsValid)
{
_db.SaveChanges();
}
}
public override void Dispose()
{
_db.Dispose();
base.Dispose();
}
tryUpdateModel return true but my model(description field) doesn't update
:(

I find out logical error:
i have to initialize BindItem.Name property instd of item.Name
Text='<%# BindItem.Description %>'

Using dropdownlists to pull data from Excel spreadsheet

Is there a way that I can use an excel spreadsheet that would then feed into my html / c# program. I have as many as 10 dropdownlists(DDL) that all have different values(example: {Ram [8, 16, 32, 64]} and another being {City[HSV, DAL, SLC, DNV]}, hard-coded into them in the html layer. Those DDL's names and values represent data that is in an excel spreadsheet. I need to write code that pulls certain data from the spreadsheet if and only if that particular value was selected within the DDL. ALL of the things I have tried looking through try to get me to import the spreadsheet and use it like a spreadsheet inside a panel or something. I need to have a way that lets me tinker with it more like a database. I need to be able to write functions/statements that operate like SQL Queries. Thank you for taking the time to read this and your attempt at helping me out.

Error handling for radiobutoon with textbox in asp.net webform

I need to display error if user selects "Other" Radio button and leaves it blank or enters wrong data in textbox. once user enters right data error goes away.
<asp:RadioButtonList ID="radyears" AutoPostBack="true" runat="server" Height="63px" Width="100px" OnSelectedIndexChanged="radyears_SelectedIndexChanged" Font-Names="Arial" Font-Size="12pt">
<asp:ListItem Selected="True" Value="15">15 Years</asp:ListItem>
<asp:ListItem Value="30">30 Years</asp:ListItem>
<asp:ListItem>Other</asp:ListItem>
</asp:RadioButtonList>
<asp:TextBox ID="txtother" runat="server" AutoPostBack="True" Font-Names="Arial" Font-Size="12pt" Width="150px" MaxLength="10"></asp:TextBox>
<asp:Label ID="lblothererror" runat="server" Font-Names="Arial" Font-Size="11pt" ForeColor="Red"></asp:Label>
Below is image showing how radiobutton shows with textbox and error message label next to textbox.
Here is image of radiobutton display
##### Here is my Try
if (radyears.SelectedValue == "Other")
{
if (String.IsNullOrEmpty(txtother.Text) || (!double.TryParse(txtother.Text, out years)))
{
lblothererror.Text = "Not Valid Input";
return;
}
else
{
lblothererror.Text = "valid number";
return;
}

Try this code :-
<asp:RadioButtonList ID="radyears" AutoPostBack="true" runat="server" Height="63px" Width="100px" Font-Names="Arial" Font-Size="12pt" OnSelectedIndexChanged="radyears_SelectedIndexChanged">
<asp:ListItem Selected="True" Value="15">15 Years</asp:ListItem>
<asp:ListItem Value="30">30 Years</asp:ListItem>
<asp:ListItem>Other</asp:ListItem>

Try this
Here is c# code

}
}

if (radyears.SelectedValue == "Other")
{
double years = 123;//Any Value
if (String.IsNullOrEmpty(txtother.Text) || (!double.TryParse(txtother.Text, out years)))
{
lblothererror.Text = "Not Valid Input";
return;
}
else
{
lblothererror.Text = "valid number";
return;
}
}
else
{
lblothererror.Text = "";
return;
}
}
and here it is

Add new record to Telerik RadGrid

I have the following Telerik RadGrid, which I'm using in C#:
<MasterTableView Width="100%" EditMode= "InPlace" ClientDataKeyNames="menuID" CommandItemDisplay= "Top">
<Columns>
<telerik:GridBoundColumn DataField="Name" HeaderText="Name" SortExpression="Name" UniqueName="Name"></telerik:GridBoundColumn>
<telerik:GridTemplateColumn UniqueName="Type" HeaderText="Type">
<ItemTemplate>
<asp:TextBox ID="Type" Text='<%# DataBinder.Eval(Container.DataItem, "Type") %>' runat="server"></asp:TextBox>
</ItemTemplate>
<EditItemTemplate>
</EditItemTemplate>
</telerik:GridTemplateColumn>
<telerik:GridTemplateColumn UniqueName="List" HeaderText="List">
<ItemTemplate>
<asp:CheckBox ID="List" runat="server" Checked='<%# DataBinder.Eval(Container.DataItem, "List") %>' />
</ItemTemplate>
<EditItemTemplate>
</EditItemTemplate>
</telerik:GridTemplateColumn>
<telerik:GridTemplateColumn UniqueName="loadAtStart" HeaderText="loadAtStart">
<ItemTemplate>
<asp:CheckBox ID="loadAtStart" runat="server" Checked='<%# DataBinder.Eval(Container.DataItem, "loadAtStart") %>' />
</ItemTemplate>
<EditItemTemplate>
</EditItemTemplate>
</telerik:GridTemplateColumn>
</Columns>
</MasterTableView>
The grid is populated with data, and working normally when editing the data.
But when I click on the Add New Record button provided by Telerik, then an empty row is added without any TextBox or CheckBox in the columns to edit in the new Row added. It's just an empty row. I presume that I have to create the controls dynamically in the called ItemDataBound event, but I didn't manage to find the actual code for this.
How do I solve this?

Please try with the below code snippet.

Hope this would help you :-)

I'm not really a fan of any of these solutions because they require the use of Session. Session has it's place but I believe it's used more as a crutch.
You're already sending the RadGrid information back to the server-side via ViewState due to the PostBack so why not use it's information instead of relying on an in-memory store.
Example of Adding and Removing an item from a Grid. Yes, it does require iterating items to rebuild a List but it's an alternative to Session so I believe it has merit.
protected void addValueToRecentTagList(string text)
{
List<string> items = new List<string>();
foreach(GridDataItem row in RadGridNewTags.Items)
items.Add(row["tag"].Text);
items.Add(text);
RadGridNewTags.DataSource = items;
RadGridNewTags.DataBind();
}
protected void removeValueFromRecentTagList(string text)
{
List<string> items = new List<string>();
bool rebind = false;
foreach (GridDataItem row in RadGridNewTags.Items)
{
if (row["tag"].Text == text)
rebind = true;
else
items.Add(row["tag"].Text);
}
if (rebind)
{
RadGridNewTags.DataSource = items;
RadGridNewTags.DataBind();
}
}

You have to insert a control in the EditItemTemplate to display in Edit or Insert mode.
Or you can add an InsertItem Template and place a control in there:
<telerik:GridTemplateColumn UniqueName="loadAtStart" HeaderText="loadAtStart">
<ItemTemplate>
<asp:CheckBox ID="loadAtStart" runat="server" Checked='<%# DataBinder.Eval(Container.DataItem, "loadAtStart") %>' />
</ItemTemplate>
<EditItemTemplate>
<asp:CheckBox ID="cbxEditLoadAtStart" runat="server" Checked='<%# Bind("loadAtStart") %>' />
</EditItemTemplate>
<InsertItemTemplate>
<asp:CheckBox ID="cbxInsertLoadAtStart" runat="server" />
</InsertItemTemplate>
</telerik:GridTemplateColumn>

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.

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();
