Hello community,

I created a xaml-control inside a windows form.
In my XAML.cs file I want to get access to a rich textbox inside this form. I declared it public but i cant get access to it...

thx in advance

What I have tried:

public System.Windows.Forms.RichTextBox rtbBill;

private void btnBill_Click(object sender, RoutedEventArgs e)
        {
            // get access to rtbCuisine here
        }

Well.... the name of the control is rtbBill not rtbCuisine to begin with.

You're welcome, I suppose. Nothing else in your posting makes any sense.

I don't have tons of experience with WinForms but I'm guessing you're using an ElementHost to host a WPF UserControl or similar? You may have to traverse the hierarchy using ElementHost.Parent. It would really help to have more of the code. What you've posted doesn't show anything relevant such as the code which hosts the xaml or the xaml itself so I doubt you'll get any meaningful responses.

If the control is a child of the current control/form, use this.rtbBill.

that does not work, cause the rich textbox is on the form and the button on the xaml file...
