I have a Grid View. The Data displays correctly. However the footer doesn't show. Can anyone tell me what is wrong ?
Below is the code:-
<asp:GridView ID="grdJLLAlloc" runat="server" AutoGenerateColumns="false" Width="400px"
ShowFooter="True" CellPadding="4" SkinID="OrigBkrAlloc">
<Columns>
<asp:BoundField DataField="Professional" HeaderText="Professional" />
<asp:BoundField DataField="Market" HeaderText="Market" />
<asp:BoundField DataField="BusinessLine" HeaderText="Business Line" />
<asp:BoundField DataField="PSBusinessUnit" HeaderText="Business Unit" />
<asp:TemplateField HeaderText="%">
<HeaderStyle HorizontalAlign="Center" Wrap="True" Width="170px" />
<ItemStyle HorizontalAlign="Center" />
<ItemTemplate>
<asp:Label ID="lblJLLAllocPercentage" runat="server" Text='<%# Eval("Percentage") %>'></asp:Label>
</ItemTemplate>
<FooterTemplate>
<asp:Label ID="lblJLLAllocTotalPer" runat="server" Text="" Visible="true"></asp:Label>

<ItemTemplate>
<asp:Label ID="lblJLLAllocAmt" runat="server" Text='<%# Eval("Amount") %>'></asp:Label>
</ItemTemplate>
<FooterTemplate>
<asp:Label ID="lblJLLAllocTotalAmt" runat="server" Text="" Visible="true"></asp:Label>
</FooterTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
Private Sub LoadJllAllocGrid()
Dim dsJLLCommAlloc As New DataSet("JLLCommissionAlloc")
Try
If m_DealId > 0 Then
dsJLLCommAlloc = oComm.GetCapForceJLLCommissionAlloc(m_DealId)
grdJLLAlloc.DataSource = dsJLLCommAlloc
grdJLLAlloc.DataBind()
End If
Catch ex As Exception
ExceptionPolicy.HandleException(ex, Common.EXCEPTION_POLICY)
End Try
End Sub
Private Sub grdJLLAlloc_RowDataBound(sender As Object, e As GridViewRowEventArgs) Handles grdJLLAlloc.RowDataBound
If e.Row.RowType = DataControlRowType.Footer Then
Dim lblTotalAmt As Label = DirectCast(e.Row.FindControl("lblJLLAllocTotalAmt"), Label)
lblTotalAmt.Text = "100,000$"
End If
End Sub
It looks like you forgot to bind the grdJLLAlloc_RowDataBound method to the GridView
<asp:GridView ID="grdJLLAlloc" OnRowDataBound="grdJLLAlloc_RowDataBound"

I have this code:
<asp:TemplateField HeaderText="Gestisci IP" SortExpression="GestisciIp">
<EditItemTemplate>
<asp:DropDownList ID="ddlGestisciIP" runat="server" AppendDataBoundItems="true"
DataSourceID="SqlDataSource3" DataTextField="GestisciIP"
DataValueField="GestisciIP" SelectedValue='<%# Bind("GestisciIP") %>'>
<asp:ListItem Text="True" Value="True" />
<asp:ListItem Text="False" Value="False" />
</asp:DropDownList>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label2" runat="server" Text='<%# Bind("GestisciIp") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
The datasource contain the value of a field selected on the current user (user id) and it can be True or False.
My problem is that I want the dropdown to always shows the 2 options True and False, but it should also have the selected value got from the datasource.
If I remove the 2 lines
<asp:ListItem Text="True" Value="True" />
<asp:ListItem Text="False" Value="False" />
it only shows the value got from the db, if I leave these lines it shows 3 values: the one got from the db and True, False added by this code.
So, how can I do this? I hope I was clear enough, thanks
IT'S DONE!
Thank you again

try this,add Onrowdatabound event to your gridview and bind your dropdownlist in that event.

First ,With the use of RowCommand Event of the Grid View , Get the value of the Edited Label into the ViewState,then Use viewstate and Handle your RowDataBound
and to upadate your data you can use roeupdate event,like follows
protected void Gridview2_RowUpdating(Object sender, GridViewUpdateEventArgs e)
{
//add code for updating values in database
}
If i understood correct, you only want the values TRUE and FALSE, so, you don't need a datasource to do this...
Remove this properties DataSourceID, DataTextField, DataValueField and SelectedValue...
Try it please.
After clicking the edit linkbutton of my gridview, I show the data on different text boxes which are not inside the gridview. I have a "Reset" button which i want to use to get back to the original values. But I am having problem to access those gridview data inside the button click handler and reset it.I tried using DirectCast() but its showing System.NullReferenceException.
<asp:GridView ID="GridView3" runat="server" AutoGenerateColumns="False" DataKeyNames="id">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton ID="lblEdit" runat="server" CausesValidation="false" CommandName="editRecord" Text="EDIT" CommandArgument="<%# Container.DataItemIndex %>"></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="id" InsertVisible="False" SortExpression="id" Visible="False">
<ItemTemplate>
<asp:Label ID="lblRecordID" runat="server" Text='<%# Bind("id") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="HANGER">
<ItemTemplate>
<asp:Label ID="lblHANGER" runat="server" Text='<%# Bind("HANGER") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns></asp:GridView>
The backend vb.net code is-
Protected Sub btnClear_Click(sender As Object, e As EventArgs) Handles btnReset.Click
Dim vID As Label = DirectCast(GridView3.SelectedRow.FindControl("lblRecordID"), Label)
Dim vHanger As Label = DirectCast(GridView3.SelectedRow.FindControl("lblRecordID"), Label)
txtID.Text.Text = vID.Text()
ddlHanger.SelectedValue = vHanger.Text 'dropdown list that's why selectedValue used
End Sub
I have copied the portion of the code cause the gridview has lot more rows. I would appreciate if anyone please show me a solution.Thanks in advance.
First remove the following:
<ItemTemplate>
<asp:LinkButton ID="lblEdit" runat="server" CausesValidation="false"
CommandName="editRecord" Text="EDIT"
CommandArgument="<%# Container.DataItemIndex %>"></asp:LinkButton>
</ItemTemplate>
And add:
<asp:CommandField ButtonType="Button" ShowSelectButton="True" SelectText="EDIT" />
That markup will allow your GridView to have an EDIT button which will switch the current selected row index correctly. System.NullReferenceException error you are recieving could be because the GridView3.SelectedRow is NULL/EMPTY, which also means GridView3 currently has NO selected index.
To make sure that GrieView3 indeed selected a ROW, you can add: the following right AFTER the
<SelectedRowStyle BackColor="Black" BorderColor="White" BorderStyle="Dotted"
BorderWidth="3px" ForeColor="White" />
right after
</Columns>
So your final GridView3 markup should look like:
<asp:GridView ID="GridView3" runat="server" AutoGenerateColumns="False" DataKeyNames="id">
<Columns>
<asp:CommandField ButtonType="Button" ShowSelectButton="True"
SelectText="EDIT" />
<asp:TemplateField HeaderText="id" InsertVisible="False" SortExpression="id" Visible="False">
<ItemTemplate>
<asp:Label ID="lblRecordID" runat="server" Text='<%# Bind("id") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="HANGER">
<ItemTemplate>
<asp:Label ID="lblHANGER" runat="server" Text='<%# Bind("HANGER") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
<SelectedRowStyle BackColor="Black" BorderColor="White" BorderStyle="Dotted"
BorderWidth="3px" ForeColor="White" />
</asp:GridView>
Then you can also use TryCast too, like so:
Protected Sub btnClear_Click(sender As Object, e As EventArgs) Handles btnReset.Click
Dim vID As String = TryCast(GridView3.SelectedRow.FindControl("lblRecordID"), Label).Text
Dim vHanger As String = TryCast(GridView3.SelectedRow.FindControl("lblRecordID"), Label).Text
txtID.Text.Text = vID
ddlHanger.SelectedValue = vHanger
End Sub
I know this question has been asked several times before and I have tried many of the suggested solutions. I am attempting to bold each row of my GridView that contains the text "Earned" or "Total" (haven't added "total" code yet). I have successfully gotten the DataBound event to fire, and I've successfully gotten it to recognize the 2 For looping statements that I use to loop through each row and column (I use labels to let me know which code blocks I've accessed and the counts are 24 rows and 9 columns), but for some reason, the code that I use to specifically determine if the cell contains the text "Earned" won't fire. I'm not sure what I'm doing wrong. Could someone take a look and help me understand what I'm doing wrong? Thank you for your help!

The method you used to access the GridView rows cells will only work with bound fields not template fields. In order to access a template field you can use Row.FindControl method.
Please try this instead in your gv_VacationDetails_DataBound method:
Public Sub gv_VacationDetails_DataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs)
If e.Row.RowType = DataControlRowType.DataRow Then
'First you need to get the template fields, which are labels as in GridView your design
Dim Label1 As Label = DirectCast(e.Row.FindControl("Label1"), Label)
Dim Label2 As Label = DirectCast(e.Row.FindControl("Label2"), Label)
Dim Label3 As Label = DirectCast(e.Row.FindControl("Label3"), Label)
Dim Label4 As Label = DirectCast(e.Row.FindControl("Label4"), Label)
'Next you can check each field value
If Label1.Text = "Earned" Then
Label1.Font.Bold = True
End If
If Label2.Text = "Earned" Then
Label2.Font.Bold = True
End If
If Label3.Text = "Earned" Then
Label3.Font.Bold = True
End If
If Label4.Text = "Earned" Then
'Label6.Text = "Inside BOLD IF"
Label4.Font.Bold = True
End If
'You can check the bound fields by looping through row cells
For Each cell As TableCell In e.Row.Cells
If cell.Text = "Earned" Then
cell.Font.Bold = True
End If
Next
End If
End Sub
I have one radio button in gridview itemplate field. But when I am selecting the radiobutton i am unable to get the id of that row. So that based on that id textbox value will be autopopulated.

You can try on the radiobutton click event to look for sender.parent.findcontrol("lblID").
this would be on the code-behind and for vb.net it would look like this:
Dim rowID as String = CType(CType(sender, RadioButton).Parent.FindControl("lblID"),Label).Text
I've got a gridview inside an update panel.
In the gridview I have an image button.
The button is used to delete a row.
In the rowCommand event of the grid view I do something like this:
protected void gvLineItems_RowCommand(object sender, GridViewCommandEventArgs e)
{
GridViewRow row = (GridViewRow)((Control)e.CommandSource).NamingContainer;
switch (e.CommandName)
{
case "Delete":
Label l = null;
l = (Label)row.FindControl("lblLineItemID");
if(l!=null)
{
long lID;
lID = Convert.ToInt64(l.Text);
BL.DeleteLineItem(Convert.ToInt64(hlID.Text), lID);
BindGrid(Session["SortExpression"].ToString(), Convert.ToInt32(rbSortGrid.SelectedValue));
}
break;

I debug this and I see the row deleted in the database (data is deleted correctly). But the gridview still shows the "deleted" row even after bind grid. Bind grid is simple it looks like this:
protected void BindGrid(string sortExpression, int sortDirection)
{
DataSet ds
ds = BL.GetLineItemGridData(Convert.ToInt64(hlID.Text), sortExpression, sortDirection);
gvLineItems.DataSource = ds.Tables[0];
gvLineItems.DataBind();
gvLineItems.Visible = true;
}
The dataset is returning the correct rows (without the deleted row) but when I look at the webpage it still shows the row that was deleted.
Edit
Someone asked for the HTML of the gridview, here it is:

Err I got it I just added this:
protected void gvLineItems_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
DataSet ds = null;
gvLineItems.DataSource = null;
ds = BL.GetLineItemGridData(Convert.ToInt64(hlID.Text), Session["SortExpression"].ToString(), Convert.ToInt32(rbSortGrid.SelectedValue));
gvLineItems.DataSource = ds.Tables[0];
gvLineItems.DataBind();
gvLineItems.Visible = true;
}
And removed the call to BindGrid from this:
protected void gvLineItems_RowCommand(object sender, GridViewCommandEventArgs e)
{
GridViewRow row = (GridViewRow)((Control)e.CommandSource).NamingContainer;
switch (e.CommandName)
{
case "Delete":
Label l = null;
l = (Label)row.FindControl("lblLineItemID");
if(l!=null)
{
long lID;
lID = Convert.ToInt64(l.Text);
BL.DeleteLineItem(Convert.ToInt64(hlID.Text), lID);
//BindGrid(Session["SortExpression"].ToString(), Convert.ToInt32(rbSortGrid.SelectedValue));
}
break;
}
}
Alternatively you can bind your GridView in the Page PreRender event which occurs after processing of control events has been completed. You don't need to hook up the datasource and bind the grid in the rowCommand event then.
