How to delete a row from GridView without affecting the Database

How to delete a row from GridView without affecting the Database - c#

I am populating a Gridview using a form with the help of AJAX.
I want to add a delete button to each row and whendelet button is clicked that row should be deleted from GridView (not hidden).
Here is my aspx code:
<asp:Content ID="Content2" ContentPlaceHolderID="Nav" runat="server">
</asp:Content>
<asp:Content ID="Content3" ContentPlaceHolderID="MainContent" runat="server">
<table>
<tr>
<td class="auto-style1">
<asp:Label ID="LabelFirstName" runat="server" Text="First Name"></asp:Label>
</td>
<td>
<asp:TextBox ID="TextBoxFirstName" runat="server" CssClass="auto-style2"></asp:TextBox>
</td>
</tr>
<tr>
<td class="auto-style1">
<asp:Label ID="LabelLastName" runat="server" Text="Last Name"></asp:Label>
</td>
<td>
<asp:TextBox ID="TextBoxLastName" runat="server"></asp:TextBox>
</td>
</tr>
</table>
<br /><br />
<asp:Button ID="ButtonSearch" runat="server" Text="Search" CssClass="auto-style3" Width="93px" OnClick="ButtonSearch_Click" />
<br /><br />
<asp:Label ID="LabelNoRows" runat="server" Text="Sorry, we couldn't find any data with this Name." Visible="false" ForeColor="Red"></asp:Label>
<asp:Panel ID="PanelAbsenceInfo" runat="server" Visible="false">
<table>
<tr>
<td class="auto-style4">
<asp:Label ID="LabelFname" runat="server" Text="First Name:"></asp:Label>
</td>
<td>
<asp:Label ID="LabelGetFirstName" runat="server"></asp:Label>

</td>
</tr>
</table>
<br /><br />
<asp:GridView ID="GridViewViewAllRequests" runat="server" AutoGenerateColumns="False" DataKeyNames="id"
OnRowCommand="GridViewViewAllRequests_RowCommand">
<Columns>
<asp:BoundField DataField="scrap" Visible ="false" />
<asp:BoundField DataField="isApproved" Visible="false" />
<asp:BoundField HeaderText="Date of Absence" DataField="requestedDate" DataFormatString="{0:MM/dd/yyyy}" />

<asp:TemplateField HeaderText="Scrap/Undo">

</asp:TemplateField>
</Columns>
</asp:GridView>
</ContentTemplate>
</asp:UpdatePanel>
</asp:Panel>
<br /><br />
</asp:Content>
And here is my cs code:
public partial class AbsenceRequestMonitor : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void ButtonSearch_Click(object sender, EventArgs e)
{
DoAction();
}
public Boolean ScraptheRequest(int id, bool action)
{
bool success = false;
success = DBOperation.ScrapAbsencedate(id, action);
return success;
}
protected void GridViewViewAllRequests_RowCommand(object sender, GridViewCommandEventArgs e)
{
//Determine the RowIndex of the Row whose Button was clicked.
int id = Convert.ToInt32(e.CommandArgument);
//Get the value of column from the DataKeys using the RowIndex.
// int id = Convert.ToInt32(GridViewViewAllRequests.DataKeys[rowIndex].Values[0]);
if(e.CommandName == "Scrap")
{
ScraptheRequest(id, true);
}
else if(e.CommandName == "Undo")
{
ScraptheRequest(id, false);
}
DoAction();
UpdatePanelInfo.Update();
}
public void DoAction()
{
string firstName = null;
string lastName = null;
firstName = TextBoxFirstName.Text.ToString();
lastName = TextBoxLastName.Text.ToString();
double PdCount = 0;
double OtherCount = 0;
if (firstName != null && lastName != null)
{
//gets student data from the Student Form
List<AbsenceMonitorData> l_studentAbsenceInfo = DBOperation.getStudentAbsenceInfo(firstName, lastName);
AbsenceMonitorData studentAbsenceInfo = l_studentAbsenceInfo.FirstOrDefault();
PdCount += l_studentAbsenceInfo.Where(x => x.reason == "Personal Day").Where(y => y.isApproved == true).Where(z => z.scrap == false).Select(a => a.daysMissed).Sum();
OtherCount += l_studentAbsenceInfo.Where(x => x.reason != "Personal Day").Where(y => y.isApproved == true).Where(z => z.scrap == false).Select(a => a.daysMissed).Sum();
GridViewViewAllRequests.DataSource = l_studentAbsenceInfo;
GridViewViewAllRequests.DataBind();
if (l_studentAbsenceInfo.Count > 0)
{
LabelGetPersonal.Text = PdCount.ToString();
LabelGetOther.Text = OtherCount.ToString();
LabelgetTotaldays.Text = (PdCount + OtherCount).ToString();
LabelGetFirstName.Text = studentAbsenceInfo.firstName.ToString();
LabelGetLname.Text = studentAbsenceInfo.lastname.ToString();
LabelGetEmail.Text = studentAbsenceInfo.studentEmail.ToString();
PanelAbsenceInfo.Visible = true;
LabelNoRows.Visible = false;
}
else
{
LabelNoRows.Visible = true;
}
}
}
}
Right now i was using the Scrap/Undo button which i want to replace it with a Delete button.
Also when i delete the row the count should be affected. (ie. Personal Days Approved, Other Days Approved and Total Days Approved)
The image shows that when i type the name and hit search, GridView is obtained.
I need to be able to delete rows from that gridview.

Change table row text and bgcolor on a listview value asp.net C

I have a listview and I am trying to change the text color and background color depending on the value of "callswaiting". This is written in C#.
I am trying to accomplish this:
If(Eval("availableAgents") < 1); Then
; If(Eval("callsWaiting" > 2) ,Then );
{
tblSheet.Style.Add("color", "black");
tblSheet.Style.Add("background-color", "red");
}
Else;
{
tblSheet.Style.Add("color", "black");
tblSheet.Style.Add("background-color", "orange");
}
End If;
Else;
{
tblSheet.Style.Add("color", "white");
tblSheet.Style.Add("background-color", "green");

.NET ListView not populating on control selection

I have a ListView in .NET that is hooked up to various CRUD methods, the select method that accepts a value doesn't seem to be working. The Data Source is supposed to be taking the value from a drop down list control, taking the selected value. when I do the configure data source method in visual studio, I select this method for my select operation:
EntReqList_byID(Int32 programID), returns List<EntranceRequirementInfo>
Then when I define parameters in the next part of the wizard, I pick control as a parameter source, with the control ID set to CertificateList, which shows the programID as the parameter from CertificateList.SelectedValue.
When I run the page, and select an item from the CertificateList, and click "Show Program", all my data is pulled except for that in the list view. My code is as follows:
The top of my page:
Please select the program credential type:
<asp:DropDownList ID="InitialCredential" runat="server" AutoPostBack="True" OnSelectedIndexChanged="InitialCredential_SelectedIndexChanged">
<asp:ListItem>[Select]</asp:ListItem>
<asp:ListItem>Certificate</asp:ListItem>
<asp:ListItem>Diploma</asp:ListItem>
<asp:ListItem>Degree</asp:ListItem>
</asp:DropDownList>
</p>
<p>
Please select a program:
<asp:DropDownList ID="CertificateList" runat="server" DataSourceID="CertificateODS" DataTextField="ProgramName" DataValueField="ProgramID" Visible="false"></asp:DropDownList>
<asp:DropDownList ID="DiplomaList" runat="server" DataSourceID="DiplomaListODS" DataTextField="ProgramName" DataValueField="ProgramID" Visible="false"></asp:DropDownList>

CredentialType.SelectedValue = "Certificate";
ProgramLength.Text = certificate.ProgramLength;
ProgramLink.Text = certificate.ProgramLink;
Activated.Checked = certificate.Activated;
WorkOutdoors.Checked = certificate.WorkOutdoors;
ShiftWork.Checked = certificate.ShiftWork;
Travel.Checked = certificate.WorkTravel;
}
}
Is there something I am missing to make it get the programID, and populate the data?

Literal Control in ASP.NET HTML Table

I have a HTML table like following in my aspx markup file.
<table runat="server" id="tblSubstantialOwners">
<tr id="tr_header" runat="server">
<td>
<asp:Label ID="lblOnwerName" Text="Name" runat="server"></asp:Label>
</td>
<td>
<asp:Label ID="lblOwnerAddress" Text="Address" runat="server"></asp:Label>
</td>
<td>
<asp:Label ID="lblOwnerTIN" Text="TIN" runat="server"></asp:Label>
</td>
</tr>
<tr>
<td>
<asp:TextBox ID="txtOwnerName1" Width="80px" runat="server" AutoCompleteType="Disabled"
MaxLength="20" />
</td>
<td>
<asp:TextBox ID="txtOwnerAddress1" Width="80px" runat="server" AutoCompleteType="Disabled"
MaxLength="20" />
</td>
<td>
<asp:TextBox ID="txtOwnerTIN1" Width="80px" runat="server" AutoCompleteType="Disabled"
MaxLength="20" />
</td>
</tr>
</table>
but when I parse through c# asp.net code, I get literal control in each cell of html table row along with my asp.net control i.e. TextBox. Why is that?
foreach (HtmlTableRow row in htmlTable.Rows)
{
if (row.ID != "tr_header")
{
for (int count = 0; count < row.Cells.Count; count++)
{
string value = string.Empty;
HtmlTableCell cell = row.Cells[count];
foreach (Control conrol in cell.Controls)
{
if (conrol.GetType() != typeof(LiteralControl))
{
if (conrol.GetType() != typeof(Label))
{
if (conrol.GetType() == typeof(TextBox))
{
datarow[count] = ((TextBox)conrol).Text;
}
}
}
}
}
}
}

it appears that you are mixing Html Tables and ASP.NET.
If you change your Html Table to:
<asp:Table runat="server" ID="tblSubstantialOwners">
<asp:TableHeaderRow ID="tr_header" runat="server">
<asp:TableHeaderCell>
<asp:Label ID="lblOnwerName" Text="Name" runat="server"></asp:Label>
</asp:TableHeaderCell>
<asp:TableHeaderCell>
<asp:Label ID="lblOwnerAddress" Text="Address" runat="server"></asp:Label>
</asp:TableHeaderCell>
<asp:TableHeaderCell>
<asp:Label ID="lblOwnerTIN" Text="TIN" runat="server"></asp:Label>
</asp:TableHeaderCell>
</asp:TableHeaderRow>
<asp:TableRow>
<asp:TableCell>
<asp:TextBox ID="txtOwnerName1" Width="80px" runat="server" AutoCompleteType="Disabled"
MaxLength="20" />
</asp:TableCell>
<asp:TableCell>
<asp:TextBox ID="txtOwnerAddress1" Width="80px" runat="server" AutoCompleteType="Disabled"
MaxLength="20" />
</asp:TableCell>
<asp:TableCell>
<asp:TextBox ID="txtOwnerTIN1" Width="80px" runat="server" AutoCompleteType="Disabled"
MaxLength="20" />
</asp:TableCell>
</asp:TableRow>
</asp:Table>
And your code to:
protected void btnSubmit_Click(object sender, EventArgs e)
{
foreach (System.Web.UI.WebControls.TableRow row in tblSubstantialOwners.Rows)
{
if (row.GetType() == typeof(TableRow))
{
for (int count = 0; count < row.Cells.Count; count++)
{
TableCell cell = row.Cells[count];
datarow[count] = cell.Controls.OfType<TextBox>().FirstOrDefault().Text;
}
}
}
}
You can get to the controls you have in your table cells directly, either by name, ordinality, or type...

Try this to get the selected Rows value
ListView1.SelectedIndex = e.NewSelectedIndex;
string id=ListView1.SelectedDataKey.Value.ToString();
//Then pass the id's value
ListView1.DataBind();
Hope it helps.

Format Decimal number to Indian Currency Format

I am using C# asp.net 4.0 in my project where i need to display price in India curreny format.
eg. my number is 12550000.00 then i want to display it as 1,25,50,000.00
But i want this to be displayed in gridview when i bind the data to the gridview,
so it can be done in markup page. where we place Eval for each Item Data Bound.
However, i would also like to explain my senario for displaying comma sepearted values.
i have a set of textboxes above the gridview where user makes entries of values and click add.
this gets add in the viewstate and the viewstate is binded to gridview.
In gridview i also have Edit button on click of it the values in viewstate is passed back to textbox on RowCommand Event of gridview. and on update click the viewstate datatable is updated and Binded back to gridview.
FOR your reference:
protected void gvPropertyConfig_RowCommand(object sender, GridViewCommandEventArgs e)
{
try
{
if (e.CommandName == "EditItem")
{
int index = Convert.ToInt32(e.CommandArgument);
hdnIndex.Value = index.ToString();
DataTable dt = (DataTable)ViewState["proeprtyConfig"];
DataRow dr = dt.Rows[index];
if (Request.QueryString["CMD"] == "Edit")
{
hdnPropertyConfigID.Value = dr["config_id"].ToString();
if (dr["is_active"].ToString().ToLower() == "true")
{
chkConfigVisible.Checked = true;
}
else
{
chkConfigVisible.Checked = false;
}
thIsActHed.Visible = true;
tdIsActchk.Visible = true;
tdbtnConfig.ColSpan = 2;
}
txtScalableArea.Text = dr["scalable_area"].ToString();
txtCarpetArea.Text = dr["carpet_area"].ToString();
txtPricePerSqFt.Text = dr["price_per_sq_ft"].ToString();

}
if (e.CommandName == "DeleteItem")
{

DataTable dt = (DataTable)ViewState["proeprtyConfig"];
DataRow dr = dt.Rows[index];
if (Request.QueryString["CMD"].ToString() == "Edit")
{
int PropertyConfigID = Convert.ToInt32(dr[0].ToString());
prConfigObj.deletePropertyConfig(PropertyConfigID);
fillData();
}
else
{
dr.Delete();
gvPropertyConfig.DataSource = (DataTable)ViewState["proeprtyConfig"];
gvPropertyConfig.DataBind();
}
clearConfigTextBoxes();

Use the "C" parameter in the ToString function, and make sure you set the globalaztion attributes.
string parseValueIntoCurrency(double number) {
// set currency format
string curCulture = Thread.CurrentThread.CurrentCulture.ToString();
System.Globalization.NumberFormatInfo currencyFormat = new
System.Globalization.CultureInfo(curCulture).NumberFormat;
currencyFormat.CurrencyNegativePattern = 1;
return number.ToString("c", currencyFormat);
}
If you want to use a different Culture (say you're in USA, and you want the Indian format) then just use the appropriate CultureInfo element rather than getting it out of the current thread.
EXTRA INFO DUE TO OP EDIT
All right, what you're wanting to do to get this into your grid, is to create a PROTECTED function which takes in the number to be converted, and returns the converted string (this is basically the code above.
Now, on the ASPX side, you need to use that function in your grid view.
So, instead of this:
<asp:TemplateField HeaderText="Total Price (in lacs)" >
<EditItemTemplate>
<asp:TextBox ID="txttotal_price" runat="server"
Text='<%# Eval("total_price") %>' />
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="lbltotal_price" runat="server"
Text='<%# Eval("total_price") %>'> />
</ItemTemplate>
</asp:TemplateField>
you'll use this templatefield:
<asp:TemplateField HeaderText="Total Price (in lacs)" >
<EditItemTemplate>
<asp:TextBox ID="txttotal_price" runat="server"
Text='<%# Eval("total_price") %>' />
</EditItemTemplate>
<ItemTemplate>
<%# parseValueIntoCurrency(Eval("total_price")) %>'>
</ItemTemplate>
</asp:TemplateField>
Note, two things. The first is that I'm still passing the UNFORMATTED value into the EDIT TEMPLATE, and that I'm not instantiating an extra LABEL in the ITEM TEMPLATE.
The reason I'm not doing the extra label, is because we just don't need it in there. That's just a bit more processor/memory overhead that you just don't need to incur.
As for passing the unformatted value to the text field, that's because it'll ultimately be easier to validate without having to parse out the commas and other string elements.
