  Hi,
  
  I want to initialize ToggleState or Checked property of the RadCheckBoxElement, which I placed in the RibbonBar control.
  Is there a chance to do this without raising the ToggleStateChanged event?

  Hello Marco,

  Thank you for the writing.
  
  I would like to suggest subscribing to the event after the control is initialized, for example:

  radCheckBoxElement1.ToggleState = Telerik.WinControls.Enumerations.ToggleState.On

   

  AddHandler radCheckBoxElement1.ToggleStateChanged, AddressOf ToggleStateChanged

   

  Sub ToggleStateChanged(sender as object, args as StateChangedEventArgs)

   

  End Sub

  I hope this helps.
  
  

  Kind regards,
  Peter

  Hello Peter,
  
  thank you for your reply.
  I made a fault, because in my logic I convert the RadItem, to the RadCheckBoxElement or the RadButtonElement, etc., with the as C# operator.
  The RadCheckBoxElement inherits from the RadButtonElement, so the event was subscibed twice.
  I corrected my logic like this example:
  
  

  foreach (RadItem radItem in items)

  {

      bool handled = false;

   

      RadRibbonBarGroup ribbonBarGroup = radItem as RadRibbonBarGroup;

      if (ribbonBarGroup != null && !handled)

      {

          this.InitializeRibbonBarItemsState(ribbonBarGroup.Items);

          handled = true;

      }

   

      RadRibbonBarButtonGroup ribbonBarButtonGroup = radItem as RadRibbonBarButtonGroup;

      if (ribbonBarButtonGroup != null && !handled)

      {

          this.InitializeRibbonBarItemsState(ribbonBarButtonGroup.Items);

          handled = true;

      }

   

      RadCheckBoxElement checkBoxElement = radItem as RadCheckBoxElement;

      if (checkBoxElement != null && !handled)

      {

          this.InitializeCheckBoxElement(checkBoxElement);

          handled = true;

      }

   

      RadDropDownListElement dropDownListElement = radItem as RadDropDownListElement;

      if (dropDownListElement != null && !handled)

      {

          this.InitializeRadDropDownListElement(dropDownListElement);

          handled = true;

      }

   

      RadButtonElement buttonElement = radItem as RadButtonElement;

      if (buttonElement != null && !handled)

      {

          this.InitializeButtonElement(buttonElement);

          handled = true;

      }

  }

  
  Best regards.
  Marco
