Asp net c listview itemupdating

Our datasource is ready to be used and fill a List View control so let’s add one right below the dropdown list. First of all we declared the Layout Template where we told that we want our items to be displayed as unordered list items.

We added a new Entity Data Source control with the same connection name “Movie Store Entities” in order to use our Entity Framework’s generated entities.

We declared we want to support Insert, Update and Delete operations through the following properties: In the above code you can see that you need to define the control you want to retrieve the parameter value from, plus it’s type and it’s respective property.

As soon as you exit the wizard your entities are ready to used. You may notice that changes have been made to your Web.config file. Add a new Web Form named Default and make sure it has a code behind file.

We need a functionality where we can select a Genre and then the List View will display the respective genre’s reviews.

So why bother figuring out how and what to select in design mode while you can hard code exactly what you want your control to do, in the mark up?

More over, mind that configuring advanced controls such as It is really easy to understand.

In design mode click on the ddl Genres list control’s smart tab and select Choose Data Source... Click Finish and finally select the Name property to be displayed on your Drop Down List control leaving the Id as the value field.

Your page with these two control should look like this right now.

Date Time values are configured to be updated automatically in the database using the default value getdate() but still, you need to provide with a Date Time value.

To overcome this problem, changed in Design mode, click the List View control, and in the properties find and double click the Item Inserting event.

This event a good place to configure a property value before actually send to the database.
