Display Rad window on click rad grid

Hi.

On the clicking of the row write this code and set NavigateUrl of your Video/Image,

RadWindowManager windowManager = new RadWindowManager();

RadWindow widnow1 = new RadWindow();

// Set the window properties

widnow1.NavigateUrl = "Window1.aspx"; //Here you changed the Url of Your Video/Image

widnow1.ID = "RadWindow1";

widnow1.VisibleOnPageLoad = true; // Set this property to True for showing window from code

windowManager.Windows.Add(widnow1);

this.form1.Controls.Add(widnow1);

thanks.
