How can I determine who controls a cluster fired < all > value change event?

Hi all

I have a cluster (control) that looks like this:

It is a single channel of data, consisting of a gauge with two needles (set point and actual), a separate digital control related to the gauge (fixed point data type), three combo boxes and a button. When the user interacts with one of these items, I generate a Modbus packet to retrieve / set the data. My current implementation uses events, one for each single command in the channel - and I have 5 channels. Is it possible to use the parameter in the event handler, and then using the source node (or similar) to determine the control that has been actually clicked? Then, I might be able to use an array of clusters for further simplification. I'm fighting to understand the source node.

Thanks for any help

  • How can I determine if I have firefox 64?

    How can I determine if I have firefox 64-bit?

    Hello

    I had a look on the details of the user agent for your version of Firefox, and it indicates that you are using a 64-bit version of Windows, but Firefox makes use of a subsystem called WoW64, which allows him to run a 32-bit version of the software as Firefox.

    There are currently no 64 bit version of Firefox, but there is a version that is in beta version (you can download it here) and the developer edition of Firefox (which you can download here). Please note that these are not fully completed versions of Firefox you may encounter a couple of issues that would be otherwise corrected before the code skips to the release.

    I hope this helps, but if not, please come back here and we can look at another solution for you.
