i have a databound DGV and need to replace the standard error graphic to my own Image so when the user clicks add new the ugly red cross icons do not show

i have read the info on MSDN and done some google searches as well as a lot of playing around with code but cant seem to get it to work


Source for this http://msdn.microsoft.com/en-AU/libr...=vs.85%29.aspx
So this is what i can understand so far and what i have tried

according to MSDN to change the standard error image you set the DataGridViewCellStyle.NullValue property for this cell style object to a null reference

So i tried

Code:
ProfilesDataGridView.DefaultCellStyle.NullValue = vbNull
However i get this error


the following exception occured in the datagridview:

system.formatException: Formated value of the cell has wrong type
BUT all that just disables the standard error image i think?

I need to know how to change the image from icon to bitmap so i can use my own png image.
