    Question 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:
    1. Dim c As Control

    2.  
    3.         For Each c In Me.Controls

    4.             If TypeOf (c) Is CheckBox Then

    5.                 CType(c, CheckBox).Checked = True

    6.             End If

    7.         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.

    Thumbs up

    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
