To prevent exceptions from being caught internally by the grid control, you can set the Dev Express. Place Link Button Edit in Item Template and Link Button Update and Cancel in Edit Tamplate of Gridview's column. Fire Grid View's Row Editing event for Link Button Edit. Fire Grid View's Row Updating event for Link Button Update. Fire Grid View's Row Canceling Edit event for Link Button Cancel. Set Command Name propery of Link Buttons according to their respective event. Set Grid View's Data Key Names Property to record ID (ID=Primary/Unique key of student table) 7.

I have to capture the current cell data when use press the edit link Button, and use the data for optimistic concurrency control.

In my case this was happening because I was binding to a List of custom objects.

Note A common mistake that a lot of people do is that they perform a databind each and every-time the Page_Load method is called.

Assume that the data source contains a calculated column.

It's value is automatically calculated by the data source, based upon the values of other fields.

Can you post the code from the page, where your Grid View is defined?

The error you get is because Find Control returns null.

This will lead to problems like "Grid View does not show updated values", "Grid View looses values changed by user". In your Page_load, this is typically only inside a block where you check to make sure that Page_Load is not being called during a post-back call.

This event occurs after the modified focused row has been saved to the underlying data source.

This enables you to provide an event-handling method that performs a custom routine, such as canceling the update operation, whenever this event occurs.

A Grid View Update Event Args object is passed to the event-handling method, which enables you to determine the index of the current row and to indicate that the update operation should be canceled.

before that i want just using Find control and casting and then retrieving all lot code. If values are same they could notify user to change the value(give new cell value).
