designmode is always false

Question

0.00/5 (No votes)

See more:

I have a user control and I have tested the value of DesigMode in different parts of source, but never get the true value and is always false.

I read that the first place that it is set to true is in load event, then I created the following event but still get false.

this.Load += new System.EventHandler(this.ReportDesigner_Load);

private void ReportDesigner_Load(Object sender, EventArgs e)
{
IsRunningByDeveloper = this.DesignMode;
}

I don't know what is wrong , I have also checked other solutions in all the sites but none of them worked .
I also used license manager as below but still in runtime mode.

C#

if (System.ComponentModel.LicenseManager.UsageMode == LicenseUsageMode.Designtime)
                IsRunningByDeveloper = true;

Any suggestions would be appreciated

The DesignMode property indicates whether the control is rendering in the design mode of Visual Studio

What is Control's DesignMode property and how to use it?[^]

I Appreciate your comment, I thought designmode is useful when you want to detect when the project is running through Visual studio or not, Is there any property to show that?

Not really. But it's safe to assume you run the debug version of your software from within Visual Studio. So you can test in your code using #if DEBUG. Like so:

#if DEBUG
bool IsRunningByDeveloper = true;
#else
bool IsRunningByDeveloper = false;
#endif

Thanks for your reply, but your solution must be set manually,
I found a command to check it:
System.Diagnostics.Debugger.IsAttached
