WebFlyPostBackMethod() attribute is not working in SharePoint WebPart ?

Based on my discussion with the developer, the error is raised because the page could not found the function, which might be caused by setting the service url incorrectly.

We suggest using similar technique in our WebDesktop sample, SimpleTypeWF.aspx, in which we set the service URL to an external form.

Please find the attached sample havin an aspx file and its code behind having two drop down lists with flypostback manager implemenation. It works just absoutely fine and when i implemented same in my SharePoint web part where on clic of a button i want to get some date asynchronously and refresh the grid with latest data asyncrhonously withough full page post back, but i am getting javascript error saying object or method is undefined. It seems even after adding attribute to the method it is not accessible in javascript..

Some of the code extract i added for WebFlyPostBackManager

1. In CreateChildControls() method.

webFlyPostBackManager = new WebFlyPostBackManager();

webFlyPostBackManager.BlockPageUIOnBusy = true;

new WebFlyPostBackManager();

webFlyPostBackManager.BlockPageUIOnBusy = true;

true;

webFlyPostBackManager.ID = "webFlyPostBackManager";

"webFlyPostBackManager";

webFlyPostBackManager.IsDynamicCreated = true;

webFlyPostBackManager.ServiceUrl = "~/Default.aspx";

webFlyPostBackManager.EnableUIMode =

Controls.Add( webFlyPostBackManager );

interSoftWebUIGrid.FlyPostBackSettings.PostHiddenFields = true;

interSoftWebUIGrid.FlyPostBackSettings.PostInputControls = true;
