DataGrid control with checkbox template column

[Ryan Lafferty]

Hi,

I have a DataGrid control with a checkbox template column, and want to
make the checkbox "disappear" when the 3rd column of the DataGrid
contains the string "number". Is what I am trying to do impossible?

This is what I have so far, but cannot get the darn thing to work:

------------------------------------------
Private Sub myDataGrid_ItemDataBound(ByVal sender As Object, ByVal e As
System.Web.UI.WebControls.DataGridItemEventArgs) Handles
myDataGrid.ItemDataBound

Dim asdf As CheckBox
asdf = CType(e.Item.FindControl("chk1"), CheckBox)

If InStr(e.Item.Cells(3).Text, "Number") > 0 Then
asdf.Visible = False
Else
asdf.Visible = True
End If
end Sub

yeah, had this problem

You have to ensure you're not in the Header or Footer template, otherwise
the checkbox won't exist.

I'm C#, so i'll put that code, then attempt the VB way

Place this around your code

if(e.Item.ItemTemplate != ListItemType.Header && e.Item.ItemTemplate !=
ListItemType.Footer)
{
//do your logic here
}

So in VB:

if e.Item.ItemTemplate <> ListItemType.Header AND e.Item.ItemTemplate <>
ListItemType.Footer then
'do your processing here
end if


That wasn't bad huh?

Thank you Grant, worked like a charm! Wasn't bad at all.


BTW:
e.Item.ItemTemplate (c#) = e.Item.ItemType (VB)
