The loading of the DataGrid's data source requires a lot of IO operations, which cannot be displayed to the UI until the data is fully read. Due to the lack of familiarity with WPF data binding, there is not much time for observecollection and other content to be studied, only a few trickery methods can be used.Set the DataGrid's data source, as long as you modify the ItemsSource property, as follows:List dataList = new list () DataGrid1. ItemsSource

SqlDataAdapter SDA = new SqlDataAdapter ();Sda. SelectCommand = cmd;DataSet ds = new DataSet ();Sda. Fill (DS);dataGrid1.ItemsSource = ds. Tables[0]; (This is the notation in WinForm)----------------------------------------------------------------------------------------------SqlDataAdapter SDA = new SqlDataAdapter ();Sda.
