Hi Zvonko,
In the Essential Studio 4.2, We have newly added a CurrentCellErrorMessage event which you can handle and display your own custom message box whenever the grids CurrentCell.DisplayWarningText (as a result of some kind of validation error) is called. Please refer to the attached sample for implementation.
Sample:
GDBGErrorMessage.zipprivate void gridDataBoundGrid1_CurrentCellErrorMessage(object sender, Syncfusion.Windows.Forms.Grid.GridCurrentCellErrorMessageEventArgs e)
{
e.Cancel = true;
}
Best Regards,
Haneef
