title: DevExpress Winforms Databinding: DisplayFormat Ignored
body: <p>I'm databinding and formatting a TextEdit control like so: </p>
  
  <pre><code>txtArea.DataBindings.Add("EditValue", _ProductItem, "Area", true, DataSourceUpdateMode.OnPropertyChanged);
  txtArea.Properties.Mask.EditMask = @"\d*\.{0,1}\d{1,3}";
  </code></pre>
  
  <p>And in the properties for this TextEdit textbox, I've set Properties -> Mask -> MaskType to RegEx.  And also, Properties -> DisplayFormat -> FormatType is Numeric and the FormatString is set to n3.  </p>
  
  <p>If the databound EditValue is set to 24.12345 then that's what is displayed in the textbox when I run the app.  But, I'm expecting to just see 24.123.  And when I click in the textbox, the value displayed is then changed to 24.123 correctly.  But when I exit the textbox (without making any changes), it's set back to the original EditValue of 24.12345.</p>
  
  <p>If I hardcode the EditValue like txtArea.EditValue = 24.12345 the initial display is 24.123 as expected.  And while in edit mode, it's 24.123 as expected.  </p>
  
  <p>It's like DataBinding is ignoring the DisplayFormat property altogether.  Does anyone have any experience with this using DevExpress controls?</p>
