Hi!
We have another issue. Here's the description of our current solution:
The problem is that whenever we do something in the grid (like insert, modify, sort, filter rows) AND change the dropdown values outside the grid the whole grid disappears. I debugged the problem and noticed that the exception comes from your code.
Debugging further I noticed that the code there throws an exception only with DropDownProviders - other providers slide trough the code without any problems. The problem didn't go away if I just stopped using the DropDownProviders in the Insert Row, but when I removed the dropdown providers from the code altogether, everything started to work again.
Is this some kind of known issue to you?
HI AriV,
I don't believe this is a known issue. It's not something I have encountered as far as I know. I'm wondering if this is only happening over ajax postbacks? I looked at our source code and saw the same code you're pointing out. If you could get me some small sample to reproduce it (attach it to this post if you could), I could check this out and work on a fix.
regards,David Young
I am getting this same error. If I remove the dropdown provider, then the error doesn't occur. I am attaching a form (and code behind) that will demonstrate the error.
Hello,
It has been a while since you made this post and if you still need any assistance with it I will be glad to help. I have tested the sample from this forum thread and I believe that the issue that you are describing is caused because in the sample the grid is bound in the Page_init event. In order to resolve this I can suggest you move this code to the Page_load event.
For additional reference please check the attached sample
If you have any additional questions on this matter please feel free to ask.
Yeah, I noticed something similar than Peggy did. The component seemed to be a bit too unstable for my taste so I replaced the implementation with something else. Hopefully you get it fixed.
and yet another piece of info - issue doesn't occur if I disable AJAX for the grid
More info - the issue only occurs if I have added or deleted a row.
I'm using 2011.1, but I tested it with the latest in 2011.2 and it still doesn't work.
