Strange bug when adding templateitem to RadGrid

[Eran]

Here is my grid, When i removed the template button the grid functions well, but when the template button is included the grid does not load well and the ui is somewhat destroyed, all the data appears in a chained string inside a box when the template button is in place:

<telerik:RadGrid OnItemCreated="gvClients_ItemCreated" runat="server" ID="gvClients" ClientSettings-EnablePostBackOnRowClick="true" CellSpacing="0" GridLines="None" Skin="Glow" DataSourceID="SqlDataSource1" AllowPaging="True" AllowSorting="True" OnSelectedIndexChanged="gvClients_SelectedIndexChanged" OnDataBound="gvClients_DataBound" AutoGenerateColumns="False">

Hi Eran,

I was not able to replicate such an issue at my end. Please take a look at the sample code snippet, make sure you have no css set that effects the styling.

ASPX:

<asp:Label ID="Label1" runat="server" Text=""></asp:Label>
<telerik:RadGrid runat="server" ID="rgrdSample" Skin="Glow" DataSourceID="dsGrid" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False">
    <ClientSettings>
        <Selecting AllowRowSelect="True" />
    </ClientSettings>
    <MasterTableView DataKeyNames="OrderID">
        <Columns>
            <telerik:GridBoundColumn DataField="OrderID" HeaderText="OrderID" UniqueName="OrderID">
            </telerik:GridBoundColumn>
            <telerik:GridBoundColumn DataField="EmployeeID" HeaderText="EmployeeID" UniqueName="EmployeeID">
            </telerik:GridBoundColumn>
            <telerik:GridBoundColumn DataField="ShipCity" HeaderText="ShipCity" UniqueName="ShipCity">
            </telerik:GridBoundColumn>
            <telerik:GridTemplateColumn HeaderText="Download" UniqueName="downloadbutton">
                <ItemTemplate>
                    <telerik:RadButton ID="btnDownload" runat="server" Skin="Glow" Text="Download" CommandArgument="<%#Container.ItemIndex %>" OnCommand="btnDownload_Command">
                    </telerik:RadButton>
                </ItemTemplate>
            </telerik:GridTemplateColumn>
        </Columns>
        <PagerStyle AlwaysVisible="True" />
    </MasterTableView>
</telerik:RadGrid>
<asp:SqlDataSource ID="dsGrid" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" SelectCommand="SELECT  * FROM [Orders]"></asp:SqlDataSource>

C#:

protected void btnDownload_Command(object sender, CommandEventArgs e)
{
    Label1.Text = e.CommandArgument.ToString();
}

Thanks,
Shinu
