Hello,
I have a task to create a Playback View with Cameras and a html page from the web server to display. User login credentials are stored in Options menu. Playback view is constructed using ViewItemUserControl.
Is it possible to access the Options from the Playback View and change Playback view as and when Options are modified?
Please let me know, how I can achieve this.
Thanks

In the Analytics Overlay plugin sample you can see how you can save a property in the Options menu and read it in another part of the plugin.
Hello,
I looked at the example code you mentioned but could not make out much out of that example.
Probably my explanation was vague. Let me try to explain in more details. I am constructing Playback View using ViewItemUserControl.cs. However this ViewItemUserControl is initialized at time of installing the plugin and after that never called. So, if I have to change an URL in that UserControl for a ViewItem, how do I achieve it. Please let me know.
Thanks
Giridhar
I guess your ViewItemUserControl has methods where it uses the URL, instead of hardcoding the URL you can read it from Options, which is what the sample show.
My ViewItemUserControl.Init() function does constructs the url, after that, if the user changes to user credentials from Options menu, how do I make the ViewItemUserControl to use it from Options menu is my question. Please let me know.
The sample “Property” is a better sample because it also shows an event handler so that you can pick up when a user change the options. You can pick up the options setting in ViewItemUserControl.Init()
If your ViewItemUserControl.Init() function does not constructs the url, what does? Without knowing how you use the ViewItemUserControl (or a different control/plugin?) to do the html page, I am unable to help. Please describe where and how the url is set in your code.

I have pasted the code for ViewItemUserControl. Let me know.

The build-in HTML viewitem does not have any refresh method. It is possible you could create your own viewitem and use .NET control.
