Thank you, Pavlina!

So you don't agree with me that there is a bug in GridDropDownColumn? Does anybody else see the blank in the first record in Category column in this demo http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/alleditablecolumns/defaultcs.aspx, or is it just me?

My datagrid is very simple, and I don't do anything in the code behind:

    
            <telerik:RadGrid ID="RadGrid1" AutoGenerateColumns="False" DataSourceID="SqlDataSource1" 
        
                AllowAutomaticDeletes="True" AllowAutomaticInserts="True" AllowAutomaticUpdates="True">  
        
                <MasterTableView Width="100%" CommandItemDisplay="Top" DataKeyNames="PersonID"   
        
                    DataSourceID="SqlDataSource1" AutoGenerateColumns="False" runat="server" >  
        
                    <Columns>  
        
                        <telerik:GridEditCommandColumn ButtonType="ImageButton"   
        
                            UniqueName="EditCommandColumn">  
        
                        </telerik:GridEditCommandColumn>  
        
                        <telerik:GridBoundColumn DataField="FirstName" HeaderText="First Name"   
        
                            UniqueName="FirstName" ColumnEditorID="TextEditor1">  
        
                        </telerik:GridBoundColumn>  
        
                        <telerik:GridBoundColumn DataField="LastName" HeaderText="Last Name"   
        
                            UniqueName="LastName" ColumnEditorID="TextEditor1">  
        
                        </telerik:GridBoundColumn>  
        
                        <telerik:GridDropDownColumn DataField="CategoryID"   
        
                            DataSourceID="SqlDataSourceCategories" HeaderText="Category"   
        
                            ListTextField="CategoryName" ListValueField="CategoryID"   
        
                            UniqueName="CategoryID" ColumnEditorID="GridDropDownColumnEditor1" >  
        
                        </telerik:GridDropDownColumn>  
        
                    </Columns>  
        
                </MasterTableView>  
        
            </telerik:RadGrid>  
        
            <asp:SqlDataSource ID="SqlDataSourceCategories" runat="server"   
        
                ConnectionString="<%$ ConnectionStrings:gContactConnectionString %>" 
        
                SelectCommand="select * from Mailing_ContactCategories " SelectCommandType="Text">  
        
            </asp:SqlDataSource>

So why is it hapenning?

Thanks,
