Check All Checkboxes

Hello,

I have a grid with several checkbox template columns. I am trying to write a method that would check all checkboxes within the grid.

Any idea?

Without any code code its hard to give you an example but just use a loop.

Code will check all checkbox controls on a form

VB Code:

Dim c As Control
 
        For Each c In Me.Controls
            If TypeOf (c) Is CheckBox Then
                CType(c, CheckBox).Checked = True
            End If
        Next

Thank you ABX, I had tried this and it is not going down to the grid's controls.

Below is my trace, it goes from Datagrid to LiteralControl without going through the grid child controls.

I was trying to avoid loops within loop, but I got it to work.

Dim item As DataGridItem
Dim i As Integer
Dim j As Integer

For Each item In DataGrid1.Items
For i = 0 To item.Cells.Count - 1
For j = 0 To item.Cells(i).Controls.Count - 1
If TypeOf item.Cells(i).Controls(j) Is CheckBox Then
CType(item.Cells(i).Controls(j), checkBox).Checked = True
End If
Next
Next
Next


If anyone has a suggestion on how to avoid multiple loops, please let know.

Thank you
