RadComboBox in grid template - different sources for Insert and Edit

[Steve Newbery]

I have a RadComboBox in an EditItemTemplate in my RadGrid. The problem is that I need different data source for the combobox in Insert and Edit modes.

How can I switch the datasource dynamically?

Hi,

I'm trying to do something similar but this example doesn't work when the EditMode property for the MasterTableView is set to InPlace.

The problem seems to be that there's no way of detecting in the ItemDataBound event that an item is being edited, i.e. e.Item.IsInEditMode always returns false when EditMode is InPlace.

Am I missing something?

Thanks,

Gary

Hi Garee,

The differences between InPlace and EditForms auto-generated editing are outlined under the following topics in the RadGrid documentation:

http://www.telerik.com/help/aspnet-ajax/grdeditmodeinplace.html
http://www.telerik.com/help/aspnet-ajax/grdeditforms.html

I believe that they can help you address the issue you are currently facing.

Kind regards,

Hi Stephen,

Thanks for the quick response.

I've read both those articles and tried using the ItemCreated and ItemDataBound events, and casting the e.Item to GridEditableItem. I'm still not able to detect a difference between an Insert and an Edit though when the EditMode is set to InPlace.

I must be missing something as I'm sure it can't be so difficult to have different behaviour for insert and update operations. I just have a simple table where I want the user to provide values for all fields on insert, but only be able to edit a subset of those fields on subsequent updates.

Can you give me any more pointers?

Cheers,

Gary

Hi Garee,



When InPlace editing is applied, the grid item is of type GridEditableItem in edit mode and  GridDataInsertItem in insert regime. Please find attached modified project. Download it and give it a try.

Hi Plamen,

That's exactly what I was after - excellent!

I wasn't aware of the GridDataInsertItem class which is why I think I got stuck on this, so can I suggest a slight change to the wording on the following section of the documentation to mention this class in addition to the GridEditableItem class.

Or possibly on the following page:

Thanks once again for your help.

Hello Garee,

Thank you for the suggestion - the information will be included for the next version of the RadGrid documentation to the Insert/Update/Delete records -> Edit Mode -> In place topic. Your Telerik points have been updated for the feedback.
