Hello M L,

As I can see from your code - you use SqlDataSource3 to populate RadComboBox1 with data.
You are trying to set the SelectedValue of RadComboBox1 to "s_page" - but there is no such field returned from SqlDataSource3 - this causes the error that you receive.

I gave up on the RadComboBox and used the 'asp:DropdownList' instead.
This worked fine.

<asp:DropDownList ID="ddl_menu" runat="server"

DataTextField="MenuText"

DataValueField="MenuId"

DataSourceID="SqlDataSource3"

SelectedValue='<%# Bind("MenuId") %>'>

</asp:DropDownList>

                                       

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
   {
       if (e.Item is GridEditFormItem && e.Item.IsInEditMode)
       {
           GridEditFormItem editform = (GridEditFormItem)e.Item;
 
           DropDownList ddl_menu_items = (DropDownList)editform.FindControl("ddl_menu");
 
           ddl_menu_items.DataValueField = "MenuId";
           ddl_menu_items.DataTextField = "MenuText";
           ddl_menu_items.SelectedValue = "MenuId";
           ddl_menu_items.DataBind();
 
            
       }
   }

I have a RadComboBox inside RadGrid Edit Form Template, it works when I insert, but when I want to edit the row, I get Exception: Selection out of range Parameter name:value.

<Columns>

<telerik:GridBoundColumn DataField="clientTypeName" UniqueName="clientTypeName" HeaderText="Relationship"></telerik:GridBoundColumn>

</Columns>

<EditFormSettings EditFormType="Template">

<FormTemplate>

<telerik:RadComboBox ID="ddlclientType" Width="120px" runat="server" DataSourceID="SqlDataClientTypes" SelectedValue='<%# Bind("clientType")%>' DataValueField="clientType" DataTextField="clientTypeName"></telerik:RadComboBox>

</FormTemplate>

</EditFormSettings>

Why is this? Is it trying to bind the clientTypeName because I used that on the column instead of the clientType and that's why is not finding the value?

Thank You!
