Show Application Page in SharePoint 2010 Modal PopUp

Recently i was creating SharePoint webpart here we need to show application page in popup. After a lot of time to searching finally we found SharePoint Popup model as solution. here we give the brief explanation of using SharePoint model popup.

call the JavaScript method in your code and pass URL as parameter as shown in below code.

 <a href="javascript:OpenDialog(_layouts/xxxxxx/xxxxx.aspx');">MyPopUp</a>

implement JavaScript method, in that calling sharepoint inbuilt method show model dialog as shown in below code.

<script type="text/javascript">

    function OpenDialog(URL)

 {

        var NewPopUp = SP.UI.$create_DialogOptions();

        NewPopUp.url = URL;

        NewPopUp.width = 400;

        NewPopUp.height = 250;

        SP.UI.ModalDialog.showModalDialog(NewPopUp);

    }

 </script>

Close the popup using HTTP context objects with window commit popup.

public void closePopUp()

        {

       Context.Response.Write("<script type='text/javascript'>window.frameElement.commitPopup();</script>");

            Context.Response.Flush();

            Context.Response.End();

            //Response.Redirect(SPContext.Current.Site.Url);

        }
