First, we’ll implement a method to databind the Grid View, which will be called whenever databinding needs to be performed.We’re using Linq to SQL to pull data from our database and bind it to the Grid View.

In my previous article Details View Rich Data Control we have learned how to use Details View using SQLData Source data control...

I'll post the ASP code, hopefully someone can help me with this one.

To get the datakey value of the selected record of the Details View control, we need to set the Data Key Names property of the Details View control. " Select Command="SELECT * FROM Sample" Update Command="Update SAMPLE SET [email protected],[email protected] Where [email protected]" Delete Command="Delete SAMPLE Where [email protected]" Insert Command="Insert SAMPLE(Code, Name,description) VALUES(@Code,@Name,@description)" runat="server"/ When the page index of the Details View control is changed, the Page Index Changed event is fired.

The Grid View 'Grid View1' fired event Row Deleting which wasn't handled. When I say manually databinding I mean not using a data source control specified as a Data Source ID, but rather setting the Grid View’s Data Source equal to the appropriate data object and calling Data Bind. NET 2.0 are familiar with how to deal with this, but since ASP.

NET 2.0 most of the examples and tutorials deal with setting the Data Source ID, which buys you a lot of automation that you may not even appreciate unless you’ve done this the old fashioned way.

The example shown here is for a Grid View, but the same types of event handlers must be implemented in roughly the same way for other data controls including the Form View, Details View, and List View. This is the final Grid View markup, so you can see the event handlers we’re going to implement.

We’ll start with binding data to the Grid View, then build up functionality from there.

The required actions for paging to work are setting the new page index, setting the Data Source, and calling Data Bind (the last two through the Bind Data method).

In addition to that, we’re resetting the Edit Index and Selected Index when the page is changed to avoid cases, for example, where you change pages and are suddenly editing a different item.

This property should be assigned with the Primary Key of the database table. We cannot retrieve the datakey values as the data is not yet bound to the details View control.

After doing this, we can retrieve the Data Key value in the following ways. So, we call Databind() method in the Page Index Changed event handler and then retrieve the datakey value as shown in the code given below.

When you manually bind the Grid View, this tracking does not occur, so we must implement some mechanism for tracking those values.
