Hi al, is there a way to display alarms in alarm client based on severity or priority using a pushbutton?

Hi, you can make use of Filters or Sorting for the severity and priority, create a push button for the filter

There is also an alarm screen as part of the Situation Awarness Library that does a lot of these things - it may be helpful to take a look at, even if it's just to see how the developer accomplished the actions so you can implement them into your own control -
