在Webform（ASP.NET）中将选定的行从一个GridView传输到另一个GridView

Question

I have two Gridview controls. In the first one I bound the data from a stored procedure using SQL, and I want to export selected rows from Gridview1 to GridView2.

This is my code for binding the data of Gridview1:

// Load the data of [Student_Registration] store procedured
// from SQL to gridview1
sqlcom.CommandType = CommandType.StoredProcedure;
sqlcom.CommandText = "Student_Registration";
sqlcom.Parameters.Add("@SSID", SqlDbType.Int).Value = Int32.Parse(LblSubjectStudyId.Text.Trim());
sqlcom.Connection = con;
try
{
    con.Open();
    GridView1.EmptyDataText = "No Records Found";
    GridView1.DataSource = sqlcom.ExecuteReader();
    GridView1.DataBind();
}
catch (Exception ex)
{
    throw ex;
}
finally
{
    con.Close();
    con.Dispose();
}

How can I do this?

Okay, first of all you need to add a check box control in item Template and then you will have to put an export button on page.

At a button click, find all the selected rows in the grid view by using value of the checked items and then convert the whole row into a data row and add it to a table.

Now bind this datatable to the gridview source.
