  Hi,
  
  I have a C1Input-Field with EditMask = “000.0000.0000.00”. My goal is to allow leaving the field empty or to enter values that suit the mask. Now when I leave the field empty, I get a PreValidationError.
  
  If the field was empty and is left untouched no error accurs.

  Meanwhile I found the solution: The databinding has to be initialized with parameter formattingEnabled set to False.

  VB.NET Code:

  inputField.DataBindings.Add(New System.Windows.Forms.Binding("Value",C1DataView,"Field",False))
