Loading On Demand - Once And Done For All in Grid

[Brian Mains]

Hello,

I have a radgrid, which has 25 records displayed.  In the grid is a GridTemplateColumn with a RadComboBox in it.  The combo box has enabled loading on demand.  What I'd like to do is when one combo box loads, load them all.  I don't know if something like that is possible?  It's the same data for all.

Thanks,

Brian

Hello Brian,

Check out the following demo which implements the similar scenario.
ComboBox / Related ComboBoxes.

Thanks,

Hey,

That's related combos, I'm talking the SAME combo value, and when I load the first, it loads the other.  I guess my answer is there though, I have to manually call requestItems() method.  However, it would be nice if there was a way to load the items for all of the combos once once is loaded... it would save on a lot of bandwidth.

Thanks.

Hello Brian,

Yes, the requestItems() method allows you to specify the filter argument. If you need to access the client objects of all RadComboBoxes easily, you can use this help topic -> section on 'Getting all combobox instances at the client-side' at the bottom.
