Hi Denis,

I'm sorry, I think I forgot about your problem.

Here is your code posted here (I needed to add space between < and % to post it )

< %  @ Control Language="VB" AutoEventWireup="false" CodeFile="AnotoDataGrid.ascx.vb" Inherits="AnotoDataGrid" % > 
<
link href="StyleSheet.css" rel="stylesheet" type="text/css" /> 
<
asp:SqlDataSource ID="SqlDataSource1" runat="server" 
ConnectionString="< %$ ConnectionStrings:AnotoOfficeConnectionString % >" 
SelectCommand="SELECT [id], [date], [vorname], [nachname], [formular] FROM [View_PenDataStore_Clients]"> 
</asp:SqlDataSource> 
<
asp:UpdatePanel ID="UpdatePanel1" runat="server"> 
<ContentTemplate> 
<asp:GridView ID="GridView1" runat="server" AllowPaging="True" AutoGenerateColumns="False" DataSourceID="SqlDataSource1" DataKeyNames="id"> 
<Columns> 
<asp:CommandField ButtonType="Button" SelectText="" 
ShowSelectButton="True" /> 
<asp:BoundField DataField="id" HeaderText="id" 
SortExpression="id" Visible="False" /> 
<asp:BoundField DataField="date" HeaderText="date" 
SortExpression="date" /> 
<asp:BoundField DataField="vorname" HeaderText="vorname" 
SortExpression="vorname" /> 
<asp:BoundField DataField="nachname" 
HeaderText="nachname" SortExpression="nachname" /> 
<asp:BoundField DataField="formular" 
HeaderText="formular" SortExpression="formular" /> 
</Columns> 
</asp:GridView> 
</ContentTemplate> 
</
asp:UpdatePanel>
