First Set AutoGenerateDel eteButton property of gridview to true. Now you will have a link button at the end of each row in gridview. When this link button is clicked a rowdeleting event of gridview will be fired. In the row deleting event you will need to call your deletion function. In the DataKeyNames property give the name of your primary key column.
Now in the rowdeleting event of gridview, you should write code similar to this:

protected void GridView1_RowDe leting(object sender, GridViewDeleteE ventArgs e)
{
//Here you will call your deletion function
// You can get the id by using this code
//string id = GridView1.DataK eyNames.ToStrin g();
}

You can also keep the id in invisible column of gridview.

Hello, Does anyone have an idea on how I can filter the data in the gridview control that was returned by an sql query? I have a gridview that works fine when I populate it with data. Now I want to look at that data and filter it based on what is in it. I know that this could have been done with data sets and data views in asp.net 1.1 but how is this done now in asp.net 2.0?

I have a GridView bound to an ObjectDataSource. I have a Button that calls GridView.DataBind. I want the row that is selected before the DataBind to still be selected afterwards. This happens automatically if the data doesn't change.

I've been googling for some time, and could not find the solution to this problem. I am testing the paging feature of gridview. I have a very simple web form on which the user can select a few fields to be included in the table, which is to be bound to the gridview. The web form looks like so (Don't worry about the stupidity of this web form for now.):
