Command Cell throws "Expecting 1 value(s) for the key being indexed, but received 0 value(s)."}

[Ankur Khator]

Hi,
I have a GridViewCommandColumn in my grid. I populate the grid, sort on the command column. Then in some operation I update the values of the GridViewCommandColumn. Upon clicking any cell of this column, I get the following exception

Message : {"Expecting 1 value(s) for the key being indexed, but received 0 value(s)."}

Please suggest what can be wrong here.

Hi Ankur Khator,

I am not able to locate the issue by looking at this exception. Also, I could not reproduce the issue with tests. Generally, it is not expected to sort the command column. Please, could you describe your scenario in detail and send us your application. This will help me locating the issue. I am looking forward to your reply.

All the best,

Hi,
I was able to avoid this problem by explicitly setting DataSource and MasterGridViewTemplate.DataSource properites of the grid to null before binding it to different dataset.

Hi Jack,
since this is a part of my bigger application, it is very hard for me to isolate this problem and send over application to you. Also since we got the workaround, it is difficult for me to committ time on this. I hope you understand.
I will surely isolate this out if I observe this again.

Thanks for your help
Ankur
