I'm using a RadComboBox inside a RadGrid. It appears I have to use a GridTemplateColumn because I want to use a custom skin for the drop down and I want to have a blank entry as the first item by default. Is there a way to do that without using a GridTemplateColumn?

Anyhow, now that I'm using the GridTemplateColumn, I'm having a problem getting the in-line editing and inserting to work. When I try to insert an item I get this error: "DataBinding: 'Telerik.Web.UI.GridInsertionObject' does not contain a property with the name 'Type'." Editing an existing record works great.

Here is my code:

    
            <telerik:GridTemplateColumn HeaderText="Type" DataField="Type" > 
        
                                        <ItemTemplate> 
        
                                            <%# Eval("Type.Name") %> 
        
                                        </ItemTemplate> 
        
                                        <EditItemTemplate> 
        
                                            <telerik:RadComboBox ID="PropertyType" runat="server"  Width="250" Height="150" 
        
                                                    DropDownWidth="300" ShowDropDownOnTextboxClick="true" MarkFirstMatch="true" 
        
                                                    ShowToggleImage="false" AppendDataBoundItems="true"  
        
                                                    DataSourceID="PropertyTypes" DataValueField="Id" DataTextField="Name" 
        
                                                    AllowCustomText="false" SelectedValue='<%# Bind("Type.Id") %>'> 
        
                                                <Items> 
        
                                                    <telerik:RadComboBoxItem Text="" /> 
        
                                                </Items> 
        
                                            </telerik:RadComboBox> 
        
                                        </EditItemTemplate> 
        
                                    </telerik:GridTemplateColumn>

Your demo "Combo In Grid" under "Application Scenarios" has this functionality except it only has in-line editing and not inserting or I would follow that.

Thanks,

Chris
