There are ways to lower the cost of the usage of the Eval method. If you are using these controls (Data-Bound web controls) for enterprise web applications with several thousands of clicks per minute, the Eval method isn't really the best solution. In this example we are NOT going to use Eval or Bind methods, we are NOT going to use Data Source controls. Our example is going to bind the data from a Data Set, edit this data and update it.We are going to do everything from the server side. This control has one very important event that we are going to heavily manipulate - Item Data Bound. Code explanation We are going to have Label controls in Item Template and Text Box controls in Edit Item Template.Thus, we have learnt how to provide edit/update/delete and insert feature for List View Control.

We have explored the basics and adding paging feature to List View control through my previous articles List View Control in ASP. Like my previous articles on List View control, we will add this feature in 2 scenarios.This will be more clear as we get to the other event handlers.After we call Data Bind method Item Data Bound event is fired.Hi, In the Configure List View Options I'm unable to select "Enable Editing, Inserting, Deleting". Also when I try to force it, the browser displays error: "Inserting is not supported by data source 'Sql Data Source1' unless Insert Command is specified."When I configure the data source of my listview and I clicked the advance the Generate Insert, Update, Delete Statments checkbox is disabled. How do I enable the checkbox in order to use the add edit delete for my listview? I had to go through about 20 other posts before I found yours. Remember, there’s a script file in the control that should open automatically (if it doesn’t, click the gray arrow on the upper-right corner of the control or right-click the control and choose Show Smart Tag), check all the available check boxes, shown in Figure 13-4. The links in the left column enable you to edit, delete, and select the relevant genres.
