Camsex crad - Gridview onrowupdating event
Now these listed features are very much required, as we list data user may want to sort it or edit it and of course paging is also necessary to show large amount of data divided into pages.
In this example, I am hiding it if the field "Scenario" of the grid shows the text "Actual" for the relevant row of the Row Data Bound event.
If this was based on roles you could use the multiview panel but not sure if you could do the same against a property of the record. In your rowdatabound event you can hide or show the button in it.

Make two tables in a database: Contact and Contact Type.
In case of the bound field’s we need to check what column it is and need to use index of that cloumn, which is little hard and even in future if we change the column order If you see the Last Template Field part in the above code, I am using the link buttons for edit, update, delete and cancel.

By default all the boundfields will be trasferred as Textboxes in Edit Mode.
To avoid this we need to keep the property Read Only as false, Then in the edit mode nothing will happenes. The reason I use Template Field instead of Bound Field is that, it is very easy to grab those controls in the codebehind if we user labels or textboxes.
So once after done with editing data, if we click update the following method will be triggered. Once we access the required fields in the code behind, we need to update the data in the database and show the updated data to the user. If the user clicks the Delete button On Row Deleting event will be fired. Going into that code we are trying to get the primary key of the employee table(Employee ID) by using Grid View Data Key Names and then This entry was posted on March 27, 2009 at am and is filed under ASP.
