Determine if preview mode

[David A.]

Hi,

I am trying to conditionally skip code when in design mode, and normally use the following:

if (LicenseManager.UsageMode == LicenseUsageMode.Designtime)
               return;

However, when previewing reports hooked up to a temporary objectdatasource, this above code does not work.  Is there a way to determine if I am in report preview mode?  The reason I ask is that I want to bypass the _NeedDataSource event if I am in VS and previewing the report.

Thanks,
David A.

Hello David,

Telerik Reporting is integrated tool, where on preview in the VS Report Designer the start application is Visual Studio.

Possible approach to handle the case is described by my colleague in the following forum thread: DesignMode property. Based on the provided explanation you can also use an approach to detect which is the running process e.g.:

public bool isInDesignMode
       {
           get
           {
               System.Diagnostics.Process process = System.Diagnostics.Process.GetCurrentProcess();
               bool res = process.ProcessName == "devenv";
               process.Dispose();
               return res;
           }
       }

I hope the above information helps you.
