  Hello,

  If a C1NumericEdit has text (“3”), if a user highlights the text and changes it (“4”), the C1NumericEdit will fire two TextChanged events. The first will be a textchange to an empty string (“”), and then the second event will be for the actual change (“4”). Would it be possible to have C1NumericEdit fire only one event if the user replaces the text in the control? (ie: “3” → “4”)

  Thank you

  Hello,

  I could replicate this issue at my end too. I am looking further into this issue.
  
  However, as a workaround you can still meet your requirement by catching the C1NumericEdit’s Text in C1NumericEdit’s “TextChanged” event as follows:
  
  [csharp] private void c1NumericEdit1_TextChanged(object sender, EventArgs e)
  
  {
  
  if(c1NumericEdit1.Text!=“”)
  
  {
  
  System.Diagnostics.Debug.WriteLine(“TextChanged event fired”);
  
  }
  
  }[/csharp]

  Following the above mentioned approach, C1NumericEdit fires its TextChanged event only once for “3”->“4”

  Let me know if this does not works for you.

  Attached is sample application for reference.

  Hello and sorry

  but the bug is not fixed in the C1TextBox.

  I’m using C1.Win.C1Input.4, version 4.0.20173.282.

  exactly the same mistake.

  The text is “190”
  
  mark the “1” and replace with “5”

  at the first TextChanged event the text “90”
  
  at the second TextChanged event the text “590”

  and now???

  Best Regards

  Herrmann
