To cancel the update operation, set the collections, if necessary, before the values are passed to the data source.Data Bind(); // then bind the gridview Yes, you are correct that is the way to bind data in gridview, but in my problem, when I clicked the column that I want to edit, it display like textbox to enter a new value, when I type a new value in that textbox in the column gridview, I can not update it that column and can not go to another row to to edit another column value.Description: An unhandled exception occurred during the execution of the current web request.Before that you need to assign Your Database table's primay key as datakey to to the gridview like (eg.i have assigned Pk ID you have to assign you database table Primary key here) Hi Raghavendra, Thank for the code, It works.
