To cancel the update operation, set the collections, if necessary, before the values are passed to the data source.
A common way to use these collections is to HTML-encode the values supplied by the user before they are stored in the data source.
we can do the same thing by using other connection method like LINQ connection and SQLCommand and stored procedure method. Data; Step 5 - Auto Generate Delete Button=”True” and Auto Generate Edit Button=”True” Step 6 –Declare SQLConnction and SQLData Adapter object for connectivity.
For understand edit update delete gridview example, First we insert records in to database and select records from database and bind it to gridview control, then update and delete record in gridview using sql dataadater method. Step 7 - Insert record to gridview and update, delete records in gridview.
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.
Upon modifying the values in textbox which come from Edit Item Template , the new values dont show in the event handler rowupdating(), instead I get the values which appear when the page was rendered.
