Check RadCheckBoxElement without raising event

[Marco]

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,

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
