"Parameter is not valid" exception in OnPaint() in Ultragrid
posted

Hi ,

I am getting Parameter is not valid exception while calling onPaint(). 

 base.OnPaint(pe);

 

There are multiple grid using a custorm grid which is calling this method.

I am resetting the grid layout for all the grids with the help of LoadFromXml() , which causes a call to onpaint() .

When i check the parameters , i see

X and Y are 0,0 ...not sure if this is the cause.

Stack Trace is somthing like this :

System.ArgumentException: Parameter is not valid.

    Hi Ashish,

    What version of the grid are you using? Do you have the latest service release?

    Exactly what X and Y parameters are you referring to? I doubt that any X or Y would have anything to do with this exception. Most likely, this is either a bug in the grid, a threading issue in your application, or you are trying to use an image in the grid and that image was disposed for some reason.

    Can you duplicate this exception in a small sample project?
