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;

webFlyPostBackManager.BlockPageUIOnBusy = true;

webFlyPostBackManager.BlockPageUIOnBusy = true;

new WebFlyPostBackManager();

webFlyPostBackManager.BlockPageUIOnBusy = true;

true;

webFlyPostBackManager.ID = "webFlyPostBackManager";

"webFlyPostBackManager";

webFlyPostBackManager.IsDynamicCreated = true;

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

webFlyPostBackManager.EnableUIMode =

webFlyPostBackManager.EnableUIMode =

webFlyPostBackManager.EnableUIMode =

webFlyPostBackManager.EnableUIMode =

Controls.Add( webFlyPostBackManager );

 

interSoftWebUIGrid.FlyPostBackSettings.PostHiddenFields = true;

interSoftWebUIGrid.FlyPostBackSettings.PostInputControls = true;

interSoftWebUIGrid.FlyPostBackSettings.PostViewState = true;

interSoftWebUIGrid.FlyPostBackSettings.PostViewState = true;

interSoftWebUIGrid.FlyPostBackSettings.PostViewState = true;

interSoftWebUIGrid.FlyPostBackSettings.PostInputControls = true;

interSoftWebUIGrid.FlyPostBackSettings.PostViewState = true;

interSoftWebUIGrid.FlyPostBackSettings.PostViewState = true;

interSoftWebUIGrid.FlyPostBackSettings.PostViewState = true;

interSoftWebUIGrid.FlyPostBackSettings.PostInputControls = true;

interSoftWebUIGrid.FlyPostBackSettings.PostViewState = true;

interSoftWebUIGrid.FlyPostBackSettings.PostViewState = true;

interSoftWebUIGrid.FlyPostBackSettings.PostViewState = true;

true;

interSoftWebUIGrid.FlyPostBackSettings.PostInputControls = true;

interSoftWebUIGrid.FlyPostBackSettings.PostViewState = true;

interSoftWebUIGrid.FlyPostBackSettings.PostViewState = true;

interSoftWebUIGrid.FlyPostBackSettings.PostViewState = true;

true;

interSoftWebUIGrid.FlyPostBackSettings.PostViewState = true;

true;

2. In WebPart code file

[WebFlyPostBackMethod()] public void MyMethodName()

{

    interSoftWebUIGrid.ClearCachedDataSource();

    interSoftWebUIGrid.RebindDataSource();

    webFlyPostBackManager.ClientAction.UpdateViewState();

    webFlyPostBackManager.ClientAction.RenderControl( interSoftWebUIGrid);

}

 

3. In JavaScript

function ClientSideShowNextTimePeriodData(objWebFlyPostBackManager)

{

      var fpb = ISGetObject(objWebFlyPostBackManager);

      fpb.ShowNextTimePeriodData();

     // Above line gives an error saying Error: Object doesn't support this property or method

}

 

Any idea why i am not able to get this method on client side even after adding the required attribute to it ?

Can you please send us a small SharePoint web part example for doing this ?

Thank you.
