Unnecessary call RefreshDataErrorInfo
posted

Hi,

i have a Grid with following settings:

...

      this.FieldLayoutSettings.SupportDataErrorInfo = SupportDataErrorInfo.None;
      this.FieldLayoutSettings.DataErrorDisplayMode = DataErrorDisplayMode.None;

...

Why the function RefreshDataErrorInfo is called?

This function is very expensive!
