I have create Dialogbox with the ajaxupload control and 2 buttons (An apply and a cancel button) The 2 buttons are registered as acceptbutton and as CancelButton. The AcceptButtonPostBack option and the CancelButtonPostBack option are true. In the PostBack actions i have defined the following code:
Code: Visual Basic.NET
Protected Sub cmdFileUpload_Abort_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim uplFileUpload_Files As EO.Web.AJAXUploader = CType(Me.dialogUpload.ContentContainer.FindControl("uplFileUpload_Files"), EO.Web.AJAXUploader)
uplFileUpload_Files.Visible = False
End Sub
After the frist click on then cancel button (Raise the error), than i can click on the button and the error are not raised. It has with visible state of the ajaxupload to do.

Hi Phillipp,
We tried similar code and it worked fine here. Can you reproduce the same error in a test page and then post complete .aspx and .vb code here?
Thanks

Hi,
We looked into the issue and noticed that the problem is caused by our controls are not being fully unloaded by ASP.NET AJAX when it performs an partial page update. We are looking into it and see how we can get our controls fully unloaded and the issue should be addressed in our next build.
In the mean time, the easiest workaround for you would be using our CallbackPanel instead of ASP.NET's AJAX UpdatePanel. Our CallbackPanel works pretty much the same as ASP.NET AJAX UpdatePanel and does not have this problem. In order to use our CallbackPanel, you would need to:
1. Replace asp:UpdatePanel with eo:CallbackPanel;
2. Remove <ContentTemplate>. Our CallbackPanel does not use a separate <ContentTemplate> tag to holds the content. It works similar to a regular ASP.NET Panel control and holds the contents directly inside its open and close tags;
3. Edit the CallbackPanel's Trigger property to include both cmdDialog and myDialog. Our CallbackPanel does not automatically treat child controls as triggers, so you want to explicitly set it;
That should get you going. Please let us know if you see anything else.
Thanks
