Please forgive me for lack of understanding about the reported problem.

I am willing to advise you further but in order to do so I would need you to elaborate on your specific scenario by providing a working simple sample that reproduce the issue and give us a step-by-step guide that we can use to observe the problematic behavior.

hi

   I give a example,  First the WebGrid display the data correct,then you click the button to refresh the webgrid using webflypostmanager, it will miss the "\r\n".

Please try to modify the code in WebFlyPostBackMethod from:

[WebFlyPostBackMethod()]
public void RaiseCooperation()
{
    InitData();

    WebGrid1.ClearCachedDataSource();
    WebGrid1.RebindDataSource();
    WebFlyPostBackManager1.ClientAction.RenderControl(WebGrid1);    
}

into the following.

[WebFlyPostBackMethod()]
public void RaiseCooperation()
{
    InitData();

    WebGrid1.ClearCachedDataSource();
    WebGrid1.RebindDataSource();
    WebGrid1.RequiresUIRefresh = true;
}

Please let us know whether it helps or not.

hi

   I try the method you give, but it doesn't work.The webgrid doesn't refresh at all. 

otherwise, I want to know why we cann't use the "WebFlyPostBackManager1.ClientAction.RenderControl(WebGrid1)".

I just want to refresh the webgrid1 only.

First, sorry for the late respond.

Our developer suspect that the issue is more related to WebFlyPostBackManager issue rather than WebGrid. The issue has been submitted under work item #963.

It is suggested to use Grid’s refresh method, WebGrid1.ClientAction.Refresh(), if you only need to refresh the grid.

Please let us know your response.
