I am now trying to use the custom button to open an aspx page to mimic the behaviour of insert file dialog.  However, whenever there is a postback happening on the aspx page, it is opening a new window and try to do the postback in the new window, which fails.

 

I am using the javascript function to open the dialog:

 

function ShowMyDialog(button) { //use CuteEditor_GetEditor(elementinsidetheEditor) to get the cute editor instance var editor=CuteEditor_GetEditor(button); //show the dialog page , and pass the editor as newwin.dialogArguments var newwin=showModalDialog("DocumentSelectionPage.aspx" ,editor,""); }

 

Can anyone let me know how I can make the post back works?

 

Thanks,

 

Richard
