Edit Form values loses value on postback following a cancelled event

[Matthew]

I run into a scenario where controls in an EditForm loses their values when performing a postback, after recently cancelling an event.

 

For example:

1. Add new item (perform InitInsert), or edit existing item (perform Edit)

2. Make changes to control values

3. If adding, perform PerformInsert command, otherwise Update command

4. I have logic that would cancel the event (whether on ItemCommand or PerformInsert level) based on some values

5. Event cancelled, fire NeedDataSource in the background by default

6. On the EditForm, perform any postback (via cancel or attempt an insert/update again)

7. The control values within the EditForm lose their value

 

I thought if I cancelled on the ItemCommand level, the control values would persist, but this was not the case.

 

Any ideas on what I could do?

Hi Matthew,

Values usually are lost if clearing them, or reminding the RadGrid.

If you only cancel the Insert event, the Insert will not happen, in fact, the insert form will stay open.

I have attached a Sample WebForms page with a Grid and I made it cancel the Insertion. If you import this into a Visual Studio project, you can run it right away. No database is or additional coding is required.

Check out how I did and if have a different scenario, modify this sample to replicate the issue and send it back to me. I will then test it on my end and check for the cause.
