I built a UserControl (TagSelect) on the assumption that I could use it multiple times on the same window.
My assumption was based on the idea that each new use of the UC would instantiate a new TagSelect object of the class. Is this a correct assumption? It looks like this is not correct.
Before going into further detail at this point, can anyone point me to a reference for issues or approaches to reusing a UC multiple times in a window.
This particular one is to be used in a DataGridRow Column. So it will be used many times.

What I have tried:

I have read everything I can find and no clear answer.

Unless you write the control specifically for the purpose, yes, every time you use the control it's a new instance.

Beyond that, you're going to have to give a lot more detail about what you're doing, what the problem is, and the code you've used.

Thank you for your response. I realize more detail is required. I will soon post a simplified example of what I am seeing. I would appreciate our input at that time.

Dave K, what is the best way to get a description and the code so you can see it? I have a .RAR file with the VS solution and in is a doc the describes intent and results. I don't see a way to attach a file to the question.

You hover over your question and click "Improve question", then post the relevant code in PRE tags. There is no facility to upload any files, and, frankly, I wouldn't trust any such files enough to download them.
OK. I have solved this issue and everything does work as I assumed.

The issue here was that old standard - Doh

I carefully created a new list for each instance of the UC, but loaded it with old objects instead of new ones.

Should have found it a lot sooner

Thank you for the time you wasted and the willingness to help
