I downloaded WebForm1.rar and have the attached sample page tested on my end. However, the sample page only has a single instance of WebDialogBox and a button. When the button is clicked, it will set the content url of WebDialogBox and invoke Show() method to have WebDialogBox appear on the client browser.

So, I decided to create a new test page based on the following information from your first post in this thread.

... I have a problem in opening a webdialogbox in another webdialogbox. ...

• Open a WebDialogBox in another WebDialogBox.

... Two webdialogboxs usea same *.aspx. ...

• Two WebDialogBox in the same .aspx file.

Everything worked smoothly, no error occur, and the two of WebDialogBox instances can be accessed without any issues.

I enclosed my simple test page as attachment. Please kindly have the attached sample tested on your end and let us know if you have different structure of the page.
