1. When i update the data in pop up window, the same time how to refresh the datagrid in main page.?

Answer 1

Close a popup by optionally setting DialogResult to true/false and then calling Close(). You can set the IsDefault or IsCancel property on a button to automatically set the result & close.

You need to provide more information for your datagrid question.
