"Parameter is not valid" internal error when clicking around ggc.

[James Blibo]

I occasionally get the fllw error below->

Message : Parameter is not valid.

Stack Trace: at System.Drawing.Graphics.set_RenderingOrigin(Point value)

... looks like an internal error and just can't seem to find what's triggering it.

Hi,

Could you please add the solution here as well

Sakshi Khurana,

Please find the shared solution below,

Are there multiple threads involved in your application? If so, please check the Knowledge Base(KB) article link below.

KB Link: https://support.syncfusion.com/kb/article/1307/how-to-used-winforms-gridcontrol-in-a-multithreaded-application

Intermittent errors can be indications of threading issues. Any calls into the grid must be done on the thread that creates it, and you can use the grid.InvokeRequired to check for this.

Here we have attached the sample, please have a look at this.

If this is not the case, please update us with a sample showing this error. That would help us to analyze the issue here and get this resolved at the earliest.
