ASPxDashboardViewer - How to change dashboard at runtime from end user interface

created 12 years ago

Hi,

I have setup an ASPxGridview in webpage together with a ASPxDashboardviewer in my ASP.net page to allow user to change the dashboard on runtime.

I have created a System.Xml.XmlDocument and load the xml from physical file created by DashboardDesigner via the XmlDocument.Load method and assign the XmlDocument.Outerxml string to the e.Dashboardxml parameter during the DashboardLoading event (DashboardID has been set also), but it return the message "Dashboard has not been found" during debugging.

Can you provide an example of loading the dashboard from PHYSICAL XML FILE (instead of loading from database)? I have gone through your Financial demo dashboard and tried the same method but still doesn't solve the problem.

I have attached the website, project folder and dashboard layout folder for your reference.

Thanks.

Regards,
Cheang

      We have researched the issue and come to the conclusion that the current version of the ASPxDashboardViewer control does not provide a direct way to force dashboard reloading. However, we have found the following workaround:

      1. Place the ASPxDashboardViewer control inside the ASPxCallbackPanel one and use its ASPxClientCallbackPanel.PerformCallback method to force dashboard refresh.
      2. From the ASPxCallbackPanel.Callback event handler, set the ASPxDashboardViewer.DashboardId property and record a new property value to a session variable.
      3. From the Page_Load event handler, read data from the session variable and set the ASPxDashboardViewer.DashboardId property again.
        I have created a sample project that demonstrates this approach. You will find it in the attachment. I have also registered a separate request to provide an easier way to accomplish this task. We will consider this functionality implementation regarding future versions.

            the link to https://www.devexpress.com/Support/Center/Question/Details/S172028 just points back here.
            I'd like to change the loaded dashboard based on a combo selection … still looking.

              Hello,

              The sample project attached to this ticket demonstrates a possible workaround. We also suggest that you consider using the ASPxDashboard control that provides the capability to load different dashboards out of the box.
