The landlord try to use DataSet or DataTable for data binding

See what you mean is to change the data that needs to be displayed
You can use c # to change the select statement of the SqlDataSource!

Or not. You can try. I don't know what you said: "You only need to bind the primary key ..." Is it a positive sentence or a question sentence?

I mean how to make the program binding and design state binding achieve the same effect.

Try to bind

Put
GridView1. DataSource = SqlDataSource1;
GridView1. DataBind();
Put it in IsPostBack.

You give it a try, after other events are executed, you can rebind the GridView.

GridView1. DataSource = SqlDataSource1;
Bind is the value of sqldatasource design state. For example, my sqldatasource1.selectcommand has changed. Then when the page refreshes, it is bound to the original sqldatasource.selectommand. .
