[Solved] Client event settings on RadGrid

[Fernandes]

Hi!

I'm using Telerik's Grid (Prometheus) version, but as soon as I add the following line of code (regarding the client settings):

<

ClientSettings Selecting-AllowRowSelect="true" EnablePostBackOnRowClick="true"></ClientSettings>

I receive the error: Sys.ArgumentNullException: Value cannot be null.
Parameter name: id.

Everything works fine, but is there any reason for this to happen? Am i doing something wrong?

Thanks in advance!

having same issue:  mine errors out when adding this line:

<

Scrolling AllowScroll="True" ScrollHeight="140px" ...

Hi Guys,

Unfortunately we are not aware of such kind of problem so any additional details would help a lot. Can you try the exact same markup in a new AJAX-Enabled web site to see if this is not something due to specific web.config settings? If you manage to always reproduce that in a sample web site, please submit a regular support ticket sending the application. We will look at it immediately and locate the source of the problem.

All the best,

I've created a brand new ajax enabled web site, added a grid with the same client events and the error appeared immediatly. I've tried to send you a small project, but in the new Telerik Support Center, the Prometheus Grid is not available as a selectable option   :S

Anyway, I´m sending the web.config as it is created by VS.

Hi,

Thank you for the code. We were able to reproduce the error locally which seems to appear in rare cases. This is definitely something with the web.config and the devs are on it.

Unfortunately I cannot say for sure if we will manage to isolate it and fix it for the Service Pack expected later today or tomorrow.

I have updated your Telerik points for your contribution on isolating the problem.
