do you want to use JavaScript or jQuery?

CHill60 20-Mar-14 8:41am

I guess VB.NET in the code behind given the tags

Sorry I don't have much idea about VB.NET.

To do this in the code behind.

VB

Protected Sub GridView1_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles GridView1.RowCommand
    If e.CommandName = "check" Then
        'Enable Editing on the GridView
        GridView1.EditIndex = GridView1.SelectedIndex
        'Assign value to the row selected
        Dim index As Integer = Convert.ToInt32(e.CommandArgument)
        'Assign selected gridview row
        Dim checkBox As CheckBox = GridView1.Rows(index).FindControl("ChkAll")

        checkBox.Checked = true 'or false or whatever based on your command.
    End If
End Sub

If you want to do it in Javascript there is a nice article on CodeProject

first you give the class name of all the checkbox of same name then call a Jqury /Javascript function in oncheckchange event of all the checkbox . In your Jquery /Javascript . Set the Check/Uncheck Attribute.
