DataGrid Footer

[Guest]

How to find a control in the datagrid footer ?

In my code below, I am trying to hide a label named lbl1 on the basis of a selected vlaue(value="test") of the dropdownlist ,both the dropdownlist and the label are in the footer of the datagrid.

An advice on where I am going wrong,would be highly appreciated

For Each datagriditem In dg1.Items
Dim str as string="test" 'this gives the value of selected item from the dropdown list in the footer
If datagriditem.ItemType = ListItemType.Footer Then
Dim lbl As New Label
lbl = CType(datagriditem.FindControl("lbl1"), Label)
If str = "test" Then
lbl.Visible = False
End If
End If
Next

Hi Shiju:

See my article here:

The code is in C#, but you should be able to find a technique to use
from the description and code, which includes finding controls in a
grid footer and header. The trick is this: the Items collection only
contains data bound items, for the header and footer you need to look
in the Controls collection.

For one thing, you do not want to use "New Label". That creates a new label.
Just say "Dim lbl As Label".

Also, you don't say what problem you have with the above code.
