I was asked to make sure when something is pasted into a Rich text box, the text when where their curse was, not at the end or start or the text.

I thought, yeah that should be straight forward, but looking around and trying a few thing I found that it harder than I thought. It does not help that the application is a winform, so outdated.

But I have found a way and its really simple and I thought I would share my simple findings!!

Click the location within your Rich text box, that you want to insert an item too.
Then click a button or call a method and within this method do the below code.




As you can see within the code, its a few simple lines of code.
In the example I only show text, but you can add nearly anything.
