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.
