Rad Application Menu right-click

[Vladimir Abramchuk]

Hi,

I have a requirement to make RadApplicationMenu to open only by mouse right-click. How can I prevent mouse left button click and 'Enter' key pressing?

Thank you in advance.

Hi Vladimir Abramchuk,

Thank you for contacting us.

In regards to your question, the correct approach is to override the OnMouseDown (respectively OnKeyDown) method and put your logic there. Please consider the following code snippet:

public class MyApplicationMenu : RadApplicationMenu
{
    protected override void OnMouseDown(System.Windows.Forms.MouseEventArgs e)
    {
        if (e.Button == System.Windows.Forms.MouseButtons.Left)
        {
            return;
        }
        base.OnMouseDown(e);
    }

    public override string ThemeClassName
    {
        get
        {
            return typeof(RadApplicationMenu).FullName;
        }
    }
}

You can override the OnKeyDown method for the cases concerning keyboard navigation.

Please note that you need to override the ThemeClassName in the custom application menu implementation as well. For additional information, please refer to this article.

I hope you find this information helpful. Should you need additional assistance, do not hesitate to contact us.
 
All the best,
