Message); } } In order for the GV to operate correctly, its data source must be available and assigned to its Data Source property. Furthermore, remember that View State is a hierarchical data structure and can only be loaded by the same hierarchy of controls or you get errors like the one you are getting.

First you didn't actually execute the update in the database,second you never close the connection (this might lead you to memory leak, thirdyou did not re-rebind your Grid View with the updated datasource.I have a Gridview with Auto Generate Columns="False".I am using a Template Field to display my Edit, Update and Cancel 'buttons' in the first column of the Grid View within respective Item Template and Edit Item Template fields.But what I would like to do is just do this: //Int32 i_ID = Convert. search Query: using (db Data Context _db = new db Data Context()) { var search Query = txt_Search_User.

So the index is never the correct index because the Load Grid() has loaded a different query to what was loaded from the first query but the data is coming from the same place. Empty) { var result = from u in _db.tbl_Users where u.

how can I use the ID of the row instead of the index as when i select the index and the Row Editiing Hits the Load Grid() the index has changed because the first query was from a search Query and the loadgrid is just a generic load Grid() to get all the columns loaded.

Service Area }; // check more than one character is entered // ======================================== if (search Query.

Service Area Id, Service Area = u.tbl_Service Area.

Text = " * Please enter at least one character in the search box."; } grd_User. Data Bind(); } } } catch (Exception ex) { Response.

So, in order to use the Row Editing event, you must provide the original data source, but don't Data Bind() or the View State will be destroyed and controls will be recreated and events will be erased and never called.
