hi I have a problem in datagrid
Actually I am having a two datagrids and some other controls in a
usercontrol. I have added this user control to a aspx page. On
clicking a link in the first data grid the second datagrid is
displayed
My first datagrid has a checkbox column added using itemtemplate.
In the usercontrol I have a button called update on which I have to
see which checkboxes are checked based on which I have to update it to
the db.
My problem is when all the controls in the usercontrol are loaded I am
able to access in the checkbox column in my first datagrid else it
throws and error
I have used the following code
Private Sub UpdateAccountDetails()
Dim dgItem As DataGridItem
Dim ctl As Object
For Each dgItem In AcctsGrid.Items
ctl = CType(dgItem.Cells(0).Controls(0), CheckBox)
If Not ctl Is Nothing Then
Dim nViewSite = CType(ctl, CheckBox).Checked
If nViewSite = True Then
'comes inside this if its checked
End If
End If
Next dgItem
End Sub
the error is

name: index

Source Error:

Line 748: ctl = CType(dgItem.Cells(0).Controls(0),
