Are you handling anything else on KeyDown or KeyPress? I have placed a textbox on a form and I can add the @ symbol to the textbox after placing focus on it

Hello:
I think the problem is with the RadRibbonBar, because when I press "Alt" the focus is there, but I don't know control it.
the idea is when i press and release "alt", the focus placed in RadRibbonBar, but when i press "Alt" and with out release it press an ascii code, for example 64 (@), it don't lost the focus.
the text editors work so, for example office word, the textbox in web pages, this box, and I want my textbox work so too.

solution it is very important for me, please answer this issue.
Thanks

It seems that you're right. I think this is a bug that you cannot use the ALT key in conjunction with the other keys in a textbox when a RadRibbonBar is on the form.

Hello guys,

I confirm the focus issue. It will be addressed in one of our next releases. However, I cannot provide you with a workaround for the time being. Andreas, your Telerik points have been updated for the feedback.

Kind regards,

Hi Daniel,

Thank you for replying.

The issue has not been resolved. I have logged it in our Feedback portal and you can find it on the following address: UI for Winforms Feedback Portal - FIX. RadRibbonBar - Pressing the alt key takes away the focus from the other controls. Feel free to add your votes or comments. As a workaround for the time being you can use the following classes:
public class MyRadRibbonBar : RadRibbonBar
{
    protected override ComponentInputBehavior CreateBehavior()
    {
        return new MyRibbonBarInputBehavior(this);
    }
 
    public override string ThemeClassName
    {
        get
        {
            return typeof(RadRibbonBar).FullName;
        }
        set
        {
        }
    }
}
 
class MyRibbonBarInputBehavior : RadRibbonBar.RibbonBarInputBehavior
{
    public MyRibbonBarInputBehavior(RadRibbonBar owner)
        : base(owner)
    {
    }
 
    protected override bool SetInternalKeyMapFocus()
    {
        if ((this.Owner as RadRibbonBar).ContainsFocus)
        {
            return base.SetInternalKeyMapFocus();
        }
 
        return false;
    }
}

Let me know if you have further questions.

Regards,
George
