  Hello Admin!
  
  I have a SpinEditor value = 3. I use ValueChanged event so do it. When value of that control to 2, I call MessageBox. But button Down of that control set yellow color (spineditor.jpg).
  I want that control not set yellow color & reset that control.
  
  Help me!
  Thank you!
  
  My code :
  
  

  private void spChangedGridView_ValueChanged(object sender, EventArgs e)

  {

          if (int.Parse(spChangedGridView.Value.ToString()) < 3)

           {

                  spChangedGridView.SpinElement.Value = 3;

                  MessageBox.Show("NO");

           }

  }

  Hello Remeo,
  
  This is a feature of our themes. In your case RadSpinEditor buttons stay in pressed state because the modal dialog intercepts all events. You can work around the issue by handling the ValueChanged event. Here is a sample:
  
  

  private void spChangedGridView_ValueChanged(object sender, EventArgs e)

  {

      if (int.Parse(spChangedGridView.Value.ToString()) < 3)

      {

          spChangedGridView.SpinElement.UpButton.SetValue(RadElement.IsMouseDownProperty, false);

          spChangedGridView.SpinElement.DownButton.SetValue(RadElement.IsMouseDownProperty, false);

          spChangedGridView.SpinElement.Value = 3;

          MessageBox.Show(this.spChangedGridView, "NO");

      }

  }

  
  I hope this helps. If you have any further questions, do not hesitate to contact me. Best wishes,
  Peter

  Thank you Admin!
  
  But that it value return not true.
  Example : you down value < 3, it call MessageBox. After you up value to 7, you down use mouse 1 click --> it value will return to 3. If it true , it will return to 6.
  
  Thanks!

  Hello Remeo,
  
  I can confirm the described behavior and it is a normal behavior. This is because you modified the Value in ValueChanged event. By design, RadSpinEditor handles a similar restriction with Minimum and Maximum properties. I would like to propose a new approach to cover your scenario:
  

  1. Handle Leave event and set Value to 3
  2. Handle DownButton MouseUP event and set Value to 3

  Consider the attached sample project.
  I hope this helps.
  
  All the best,
  Peter
