Diagram Symbol Designer Error on Startup

[Cory Green]

Hello,

I am attempting to use the Symbol Builder for custom symbols for my Diagram control, however when starting the Diagram Symbol Builder or Diagram Builder, it instantly gets a .NET Object not found error.

The error is:

************** Exception Text **************

System.NullReferenceException: Object reference not set to an instance of an object.

   at Syncfusion.Diagram.Base.Wizard.DiagramLoadBaseWizard.SymbolDesigner_Click(Object sender, EventArgs e)

   at System.Windows.Forms.Control.OnClick(EventArgs e)

   at System.Windows.Forms.Button.OnMouseUp(MouseEventArgs mevent)

   at System.Windows.Forms.Control.WmMouseUp(Message& m, MouseButtons button, Int32 clicks)

   at System.Windows.Forms.Control.WndProc(Message& m)

   at System.Windows.Forms.ButtonBase.WndProc(Message& m)

   at System.Windows.Forms.Button.WndProc(Messag& m)

   at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

Any one else experience this??

Hi Green,

 

Reported Issue: An Exception occurs while starting the Symbol Designer using the Wizard window.

 

We tried to reproduce the reported issue, but we were unable to do so. Normally, the Wizard window opens when dragging and dropping the Diagram or Palette from the Toolbox. However, in the Symbol Designer, it's not needed to drag and drop the diagram. In this case, the diagram is created only when the New button is pressed.

 

Kindly share the code you have implemented in your application to open the Wizard window. This will help us to validate the reported issue accurately. We have also provided the tested sample for your reference.

 

Kindly share a sample with the reported issue or reproduce the issue in the provided sample.

 

Regards,

Arun Kumar S

The solution you provided for the Symbol Designer works! Thank you.

 May be a corrupted install on my end? I opened the Wizard directly from the Diagram control.

If you have previously used the Symbol Builder, check if any configuration or state files are corrupt. You might consider deleting or renaming user settings related to Syncfusion.
