HI 

Can someone help me here... 

I have a grid with a popup edit form that seems to timeout, so that when the Update button is clicked there is an exception error (seems to be a 404) and the data entered in the form is lost. The timeout seems to be at about 20 minutes as per the default session value. Before that point the Update works entirely as expected.

Access to the grid requires a login which is maintained in a session variable, so may be is related to that ?  I am not sure because
I have increased the session timeout in web.config as below.

Is there something timing out in view state that needs to be increased?  Please help. Client users are getting mad at losing their inputs...

Thanks

Clive

Hello Clive,

By default RadGrid does not use Session to persist any of its settings. However, if you have enabled the ViewState to be persisted in Session you may observe the reported behavior. Please ensure that your viewstate is not persisted in session.

In addition in case you use RadCompression, please ensure that you have not enabled compressing viewstate in session.

I hope this helps.

Mea Culpa...

It turns out the root cause was that on the remote site I had not increased the database column to nvarchar(max) as I had on my development machine, and one particular uses was entering more than the expected number of characters, causes an exception error when the Update link was clicked, which was gracefully handled and seemed like a timeout.

Doh!
