Related Combos in Grid: How to Update?

[Peter O'Connor]

I have a radgrid with AllowAutomaticInserts ="True" and AllowAutomaticUpdates="True" and EditMode ="EditForms".  This grid is bound to a telerik:OpenAccessLinqDataSource.  Everything works fine, records are displayed, and user can edit and insert records.
 
Now I have this same scenario, but I need one of the combos in the grid to be populated according to the selected item in another combo in the same grid (during insert or update).  This I have done and works fine (using OnSelectedIndexChanged), but the value in the freshly populated combo is not automatically picked up by the grid during inserting or updating.
 
I have seen examples using code behind to save the record but my quesion is this:
 
I like the automatic display and save of the radgrid using automaticupdates and automaticinserts with virtually no code behind.  Is it possible to keep this model and still have the related combo's in some way (i.e. to get the saving of records without resorting to much or any code behind)?
 
Thanx

Hello Peter,

You could populate the combo by using JavaScript. Please check out this demo where it is demonstrated how you could do that. Also you could take a look at the Related Resources tab for more information.

All the best,
