View 2 RepliesThe grid view row command does not execute on my production environment. This is a intermittant issue. I am not able to reproduct the exact steps but it does occur too often.
I have a load balanced environment with 2 identical servers in the farm. The servers are running on IIS 7.5
The other scenario in which I observe this is when the session times out. In that case the grid view events are lost. But this scenario is not a priority for me. I need to resolve the first scenario.
Any help on this or some useful links on "Understanding the session" or "understanding the complete event firing and execution" is welcome.
An update: we are overriding the PageStatePersister as:

View 5 RepliesI am doing a online web application whereby user is able to enter in new template as well as search for template. The Add template is located outside the grid view and if user clicks on the button, it will load the grid view that is populated with data as there is a row of empty fields at the bottom. However when I click on the Add Template button, the grid view does not appear.
This is my business logic that I used it to search for records as well to click on the Add Template button to add in new records:

View 4 RepliesI know that variations of this same question have been posed numerous times - but I can't quite seem to find the exact solution.
I would like any row in my gridview where the boolean field "Approved" is True to be shaded gray. Here is the code that I'm using, but every row ends up being gray, regardless of the value in that "Approved" field. My guess is that I'm not correctly evaluating the boolean value in this field (which is actually a yes/no field in MS Access), Not sure if I should be reading that value as "-1", "Yes" or "True" or "NotNull"? Anyway, here is the code:
