Hello Carlos,

You can achieve this by looping through each GridDataItem and access each CheckBox using FindControl method. Then check whether these CheckBoxes are checked or not. Sample code is given below.

VB.NET:

Protected Sub Button1_Click(sender As Object, e As EventArgs)
    For Each item As GridDataItem In rggrupos.Items
        'loops through each grid item
        Dim chkname As String = ""
        Dim chk1 As CheckBox = DirectCast(item.FindControl("chkrespseg"), CheckBox)
        ' access first checkbox
        If chk1.Checked Then
                ' get the checkbox name if its checked
            chkname = TryCast(rggrupos.MasterTableView.GetColumn("temprespseg"), GridTemplateColumn).HeaderText
        End If
        Dim chk2 As CheckBox = DirectCast(item.FindControl("chkatender"), CheckBox)
        If chk2.Checked Then
            chkname += "," + TryCast(rggrupos.MasterTableView.GetColumn("tempatender"), GridTemplateColumn).HeaderText
        End If
        'similarly check all other checkboxes
        Response.Write(chkname)
        Response.Write("<br/>")
    Next
End Sub

Thanks,
Princy.

            Dim chk1 As CheckBox = DirectCast(item.FindControl("chkrespseg"), CheckBox)
            ' get username
            usuario = item("usuario").Text
            ' access first checkbox
            If chk1.Checked Then
                ' get the checkbox name if its checked
                chkname = TryCast(rggrupos.MasterTableView.GetColumn("temprespseg"), GridTemplateColumn).HeaderText
            End If
            Dim chk2 As CheckBox = DirectCast(item.FindControl("chkatender"), CheckBox)
            If chk2.Checked Then
                chkname += "," + TryCast(rggrupos.MasterTableView.GetColumn("tempatender"), GridTemplateColumn).HeaderText
            End If
            'similarly check all other checkboxes
            Response.Write(chkname)
