Re: label in footertemplate of datagrid

<asp:DataList ID="dlCart" runat="server"
OnItemDataBound="dlCart_ItemDataBound">

In the script:

Sub dlCart_ItemDataBound(sender As Object, e As DataListItemEventArgs)
If e.Item.ItemType = ListItemType.Footer
Dim dblTotal As Double
dblTotal = 'calling a function which returns a Double
Dim TotalLabel As Label = CType(e.Item.FindControl("lblTotal"),
Label)
TotalLabel .Text = dblTotal
End If
End Sub

Eliyahu, could you please show me a small example of what you have
suggested? I haven't done anything like that anytime.

Handle ItemDataBound event. Detect the footer item by the ItemType. Use
FindControl ("lblTotal") to locate the label inside the footer item.

How can I place a Label control in the FooterTemplate of a DataList
control?

I tried this

<script runat="server">
Sub Page_Load(obj As Object, ea As EventArgs)
Dim dblTotal As Double
Dim sqlReader As SqlDataReader

dblTotal = 'calling a function which returns a Double
sqlReader = 'calling another function which returns
SqlDataReader

dlCart.DataSource = sqlReader
dlCart.DataBind
lblTotal.Text = dblTotal
End Sub
</script>

<form runat="server">
<asp:DataList ID="dlCart" runat="server">
<HeaderTemplate>
<table>
<th>ID</th>
<th>Product</th>
<th>Unit Price</th>
</tr>
</HeaderTemplate>
<ItemTemplate>
<tr>
........
</tr>
</ItemTemplate>
<FooterTemplate>
<tr>
<td colspan=2>TOTAL:</td>
<td><asp:Label ID="lblTotal" runat="server"/></td>
</tr>
</table>
</FooterTemplate>
</asp:DataList>
</form>

But it throws the error

Name 'lblTotal' is not declared.

pointing to

lblTotal.Text = dblTotal

How do I add a Label within the FooterTemplate of a DataList so that
the total can be displayed under the Unit Price column? Or is there any
other way by which I can display the total under the Unit Price column
in the DataList?
