Thank you. What you described should be perfectly doable, it's just a question of the right approach. It seems that you are on track; if you run into problems, please ask again.

Hello

Here is some details on what i want to do
I have to develop OPC Client application which will connect to an OPC server developed by me as well. The goal is to send some commands to OPC Server (by setting the value of Boolean OPC tags). The OPC sever must do some treatment when it receive these commands and then must response to client that it finished its task. it must inform on progress of completing the task as well.
The client has some buttons activated or not, depends on the values of OPC server tags. It also has a progress bar to show the progression of opc server task.
I thought to create the client as a user control, as i would like to import it to some supervision software.
That is a little description of project.
For the moment I’ll use the feedback of item_changed event to manage the animation.
Thanks

The Live Binding should work the same with standard (Microsoft-provided) controls, your own controls, or 3-rd party controls - as long as we talking about the usage as envisioned in the documentation, i.e. you bind to top-level properties of such a control, from its parent form.

Your scenario might be a bit more involved, and I am not sure it will work right away - but we are certainly interested in knowing what the users want to do with our component, and possibly advise on how to do it, or even improve the product. Can you please provide more details, such as:

- do you use the live binding simply to manipulate properties of the user control from its parent form (as described above - the supposedly well-supported scenario), OR
- do you use the live binding inside the user control, to properties of its constituent controls, OR
- are you trying to somehow manipulate properties of controls inside the user control?

Where are the DABinder (or UABinder) and BindingExtender placed? Are they on the design are of your user control, or on the parent (form)?


Thank you

Hi everybody

I'm trying the “QuickOPC .Net” and I have a question for data binding functionality.
Is it working with custom or user control as well?
I created a project windows forms and user control and I have a problem with data binding the windows controls (textbox, progress bar, etc) placed in user control, but no problem with the windows controls placed directly on windows form.
Thanks for your help
