Open Asp.net Application in Fullscreen using javascript

Sometimes, we may have a requirement to open the asp.net application developed, to be opened in full screen mode. To accomplish this, below is the code, in login page, after verifying credentials we redirect user to home page.

So now using javascript, we have to use window.open and its fullscreen properties to open home page as follows:

StringBuilder popupScript = new StringBuilder();

popupScript.Append(“<script language=’JavaScript’> window.name = ‘windowname’;open(”, ‘windowname’); window.close();window.open(‘home.aspx’, ”, ‘fullscreen=yes,status=yes,scrollbars=yes,titlebar=no,addressbar=no’);</script>”);

ScriptManager.RegisterStartupScript(this.Page, Page.GetType(), “PopupScript”, popupScript.ToString(), false);

On Logout, you can write the same script with fullscreen = no

Above code will also bypass the alert message we are getting when redirecting to another page using window.open in javascript.

It will by pass the message prompted

“The Web page you are viewing is trying to close the window” Do you want to close this window?
