Question

I have a Telerik’s RadGrid which has 2 columns like this:

<Columns>
 <telerik:GridBoundColumn HeaderText="AirlineCode" UniqueName="AirlineCode" DataField="airlineCode" />
 <telerik:GridBoundColumn HeaderText="FlightNumber " EditFormColumnIndex="1" DataField="flightNumber" />
 ... 
 ... 
 ... more code, but unrelevant to the question here.
</Columns>

I am supplying the data for both columns in the relevant NeedDataSource() function.

So it renders correctly like this:

 | AirlineCode      |      FlightNumber   | 
 ------------------------------------------
 | Delta            |      2393           | 
 | Southwest        |      345            | 

But now my requirement has changed a little bit.

For viewing, I want to merge them together and show it like this:

 |     Flight             |
 --------------------------
 |     Delta-2393         | 
 |     Southwest-345      | 

However, while editing the rows the user should be able to edit “AirlineCode” and “Flight Number” separately. And the values should still be correctly maintained in the datasource.

I know that if we want the user to “View” and “Edit” differently, we would have to use .

So I am trying something like this:

<Columns>
 <telerik:GridTemplateColumn EditFormColumnIndex="0" HeaderText="Flight">
   <ItemTemplate>
  <%#DataBinder.Eval(Container.DataItem, "airlineCode")%>
  <asp:Literal runat="server" Text="-"></asp:Literal>
  <%#DataBinder.Eval(Container.DataItem, "flightNumber")%>
   </ItemTemplate>
   <EditItemTemplate>
  <telerik:GridBoundColumn HeaderText="AirlineCode" UniqueName="AirlineCode" DataField="airlineCode" />
  <telerik:GridBoundColumn HeaderText="FlightNumber " EditFormColumnIndex="1" DataField="flightNumber" />
   </EditItemTemplate>
 </telerik:GridTemplateColumn> ... 
 ... 
 ... more code, but unrelevant to the question here.
</Columns>

But its not working.

Those 2 lines inside are giving warnings:

Element ‘GridBoundColumn’ is not a known element. This can occur if there is a compilation error in the Web site, or the web.config file is missing.

Probably I am doing it wrong. Need help.

Any help is appreciated.

It has been a while since I used the radgrid, but in your edit template I believe you need to remove the GridBoundColumns and put two textbox controls separated by the dash. Then use your Databinder to fill those txt boxes. Sorry I can’t be more concise as I’m typing on my iPhone and can’t test. I will followup with you when I am in front of my machine.

Good luck!
