Start "session" on click?

Hi all,

I'd like to use a button to start a "session" in which stuff happens until I click the button again (like an edit session only different behavior).

As best I can tell, when I click the button, it speeds through the behaviour and immediately exits. That is, it views it as a one-time thing instead of as a switch.

How can I change this to more of a turn-on, turn-off thing?

Edit to give a (not the actual thing) example: a counter between button clicks. Count until I click the button again.

Hi Alfred,

To implement a switch/toggle like this, your code needs to manage the "state" of the switch (on or off).

If you already have a state management mechanism, just use that.
If you do not, I would recommend reading up on standard support for this in the SDK, see this link for example: https://developers.arcgis.com/documentation/arcgis-pro-sdk/tutorials/manage-the-pro-ui-with-conditions/
- Or, just now Gemini gave me a pretty good, simplified summary that cut through some of the noise in this article.

Regardless of which way you go, essentially:

When your add-in initializes, initialize your state to desired default, e.g. `stateMyButtonEnabled = true`
When user clicks button flip the switch e.g. `stateMyButtonEnabled = !stateMyButtonEnabled `

At any point you can check `stateMyButtonEnabled` to know for example if the button is currently enabled or not.

If you go with Pro "conditions", the syntax for getting/setting state is a bit different, but conceptually similar.

```

// from Gemini with prompt "arcgis pro .net toggle button state"

protected override void OnClick()
{
// Check if the state is currently active
if (ArcGIS.Desktop.Framework.State.Contains("stateMyButtonEnabled "))
{
// If active, deactivate it
ArcGIS.Desktop.Framework.State.Deactivate("stateMyButtonEnabled ");
}
else
{
// If inactive, activate it
ArcGIS.Desktop.Framework.State.Activate("stateMyButtonEnabled ");
}
}

```

Good Luck
