Question

I am using a Checkbox outside of a datagrid. When i select the check box autopostback is true, and this would then show the image, but i cant access the images within the datagrid with that script. If i use a seperate image outside of the datagrid the script works. How can i get this script to work finding when the checkbox out side of the datagrid is checked to then show the image within the datagrid?

The script i am using is

<script runat="server">

    Sub Check(sender As Object, e As EventArgs)
        If checkShowImages.Checked Then
                img.Visible = True

        Else
            img.Visible = False
        End If
    End Sub

</script>

Try this(Assuming your checkbox‘s id is “CheckBox1” & DataGrid‘s Id is “Datagrid1”)…

Sub Check(sender As Object, e As EventArgs)
    For Each r As DataGridItem In Datagrid1.Items
        Try
            r.FindControl("img").Visible = CheckBox1.Checked
        Catch ex As Exception

        End Try
    Next
end sub  

Hope this helps. Good luck.
