Hi,
Try this:

C#

SqlDataSource1.DataSourceMode=SqlDataSourceMode.DataReader;
SqlDataSource1.SelectCommand = "select * from table1 where name='"+txtName.Text+"'";
SqlDataSource1.ConnectionString = ConfigurationManager.ConnectionStrings["MyConString"].ConnectionString;

//Now rebind the grid;
GridView2.DataSource = SqlDataSource1;
GridView2.DataBind();

// Changing sqldatasouce to datatable
//create dataview from sql data source 
DataView dv = (DataView)SqlDataSource1.Select(DataSourceSelectArguments.Empty);
//convert dataview to datatable
DataTable dt = dv.ToTable();
//Now dt is the table with all the values.
