Hello,

I've been following this post:
http://www.infragistics.com/community/forums/p/29234/171938.aspx#171938
but seems unresolved.

I'm using a custom control that inherits from UltraCalendarCombo. When the user types an invalid date text, I would like the control retains the focus with the invalid text instead of the last valid value with an error message through an error provider component.

I've achieved to show an error message in the control and retain the focus. However, I cannot retain the invalid text and set the control in edit mode.

The problem for me is to cancel the Leave (OnLeave) or LostFocus (OnLostFocus) events.

I've tried something like this:

  protected override void OnEnter(EventArgs e)
  {
      // Invalid is set to true in OnValidationError and
      // OnLostFocus when the text cannot be parsed to a DateTime
      if (!this.Invalid)
      {
                this.Appearance.BorderColor = SequelUltraStyle.ColorFocusedBorder;
                base.OnEnter(e);               
      }
      else
      {
                // Keep the focus but not in edit mode.
                this.SetFocus();
      }
      this.Invalid = false;
  }

  protected override void OnLeave(EventArgs e)
  {
            // Invalid is set to true in OnValidationError and
            // OnLostFocus when the text cannot be parsed to a DateTime
            if (!this.Invalid)
            {
                  this.Appearance.ResetBorderColor();
                  base.OnLeave(e);
            }
            else
            {
                 // Keep the focus but not in edit mode
                 this.SetFocus();
            }
  }

Is there any workaround to get what I want?

P.D. I'm using Infragistics2.Win.UltraWinSchedule.v10.3

Thanks!
