Download source code for Binding, Adding, Editing, Updating, Deleting, Paging and Sorting records in List View Control The asp: List View control supports data editing, insertion, deleting, paging and sorting like another powerful control Grid View.

But - unlike the Grid View, it provides us with complete control over the html markup generated like Data List or Repeater control using templates and styles.

So far, I have been messing with the on Item Updating and on Item Deleting events but I can't seem to get the values from the item properly. I used the code from Imar's book to create a guid and store the file in the project on the server.I need to get the the id of the item and the filename from the control so I can update the new filename in the database and I would like to get the old filename so I can delete it off the server. S - I know this is a lot to ask, but would it also be possible that when they press the edit button that the file upload control will already have the original file loaded into into it?If someone can show me how to get this working than I should have no trouble getting the id from the on Item Deleting event so that I can also delete the file from the server when the item gets automatically deleted from the listview. The reason why I ask is because when they click edit, the file upload control is blank so if they just wanted to edit some other fields they would have to re-upload the file again.Without writing a line of declarative markup or server-side source code, the page developer gets a decent out of the box editing interface.Namely, each field in the Grid View or Details View is rendered in its editing interface; Bound Fields display a Text Box control while Check Box Fields display an enabled checkbox.
