Please try to set the layout settings OnAfterInitialize client side events.

e.g

function WebGrid1_OnAfterInitialize(controlId)
{
			var WebGrid1 = ISGetObject(controlId);
			WebGrid1.LayoutSettings.InitialView = "PivotChartView";
			return true;
}

Somehow on your scenario, every you process the other WebPart, the settings reset to GridView. Could you let me know which WebPart you are using? ASP.net or SharePoint? If you maximize/minimize the WebPart, will the page do FullPostback or Flypostback?

The WebPart I'm using is ASP.NET Web Part, and when the Web Part is minimized/maximized, the page will do FullPostback. So, to eliminate those flickers occured when a page is refreshed I used an update panel. To help you figure out my situation, I attached here my sample.

If I set the layout settings OnAfterInitialize client side events as you said, then I need to know the current view of the grid (PivotChart or Grid). How can I know this? When user click on buttons Grid/PivotChart, is there any event raised?

When I used an update panel, after click minimize/maximize on other web parts, the grid turns into no rows there.

Kindly advise.

Thanks a lot,

Hi,

I can replicate the issue from your sample. I will forward this to our developer. Btw, your WebPartsManager should be put inside UpdatePanel, not outside.
