I have a RichTextBox that I wish to fill with RTF text at design time. This does not mean doing this:

richTextBox1.Rtf = @"<a bunch of rich text>";

which actually assigns the value at run time (or does it?).

I have created a project resource file called "TextResources.resx" with a resource named InstructionsRTF with a Value containing the rich text. How is this to be bound to the RichTextBox at design time?

Edited to add:

@hans-passant is correct, although the exact code I ended up using differs somewhat:

rtfInstructions.Rtf = TextResoures.InstructionsRTF;

where TextResources is the TextResources.resx in the project.

• winforms
• richtextbox

RichTextBox doesn't support binding. If it is already a precooked resource then trying to support this at design time doesn't make sense. It is just one line of code in the form constructor:

    public Form1() {
        InitializeComponent();
        richTextBox1.Rtf = Properties.Resources.instructionsRTF;
    }

If you want to get more adventurous at design time then that's possible too. You can create a UITypeEditor that lets you edit the RTF at design time. Code is here.
