Hi,

I'm having an issue that i spent all day yesterday trying to resolve. I'm hopeful that you can help me. I'm using rad grid and javascript as my data source. My first column which is a combo box wont let me bind. In the rad combo box settings if I set allowcustomtext="false" it will bind but the first item in the grid is automatically selected so that's not what I want. I'd like to have allowcustomtext="true" to give the user the option to enter an item or select an item but when I set allowcustomtext="true" it does not bind. I've attached 2 screen shots. first which allowcustom text false and the other allow custom text true and you can see the difference.
<telerik:GridTemplateColumn DataField="Item" UniqueName="Item">
                   <ItemStyle />
                   <ItemTemplate>
                     <telerik:RadComboBox ID="ddlItems" runat="server" AutoPostBack="false"
                           DataSourceID="objItems" DataTextField="Items" DataValueField="Items"
                           Skin="Silk"  OnClientDropDownOpening="DropDownOpening"
                           OnClientSelectedIndexChanged="ItemValueChanged" EnableViewState="true"
                           AllowCustomText="false"   Width="150px" Height="150px"
                           ondatabound="ddlItems_DataBound" OnItemsRequested="ddlItems_Requested" CssClass="SelectedItem"
                           FocusedStyle-BackColor="#fff6dc" Text='<%# Eval("Item") %>'>
                   </ItemTemplate>
               </telerik:GridTemplateColumn>
thanks,
Ron.

Hi Ron,

If you are using the RadGrid with client side data binding you need to assign values to the combo box manually on the client. Also you need manually to set values to the template column's cells when the RadGrid is not in edit mode. On the following link you can find an example of RadGrid client side binding with template column:
http://demos.telerik.com/aspnet-ajax/grid/examples/client/databinding/defaultcs.aspx
Also more information about client side data binding you can find here:
http://www.telerik.com/help/aspnet-ajax/grid-client-side-binding.html

I hope this helps.
