Disable some functionalities if any UI button is missing

[JohnP18]

Hi,

I have gotten a use case where if button in an Addin UI is missing somehow  I have to disable other functionalities. So basically if that button is not visible in the UI then how to disable other functionalities dependent on that button because I don't want user to use those functionalities.

Any help!

Hi,

1. Create new condition in module daml

2. Deactivate created condition in add-in module Initialize method

        protected override bool Initialize()
        {
            FrameworkApplication.State.Deactivate("your_condition_name");
        }

3. In your specific button constructor activate created condition

        public YourSpecificButton()
        {
            FrameworkApplication.State.Activate("your_condition_name");
        }

4. Add condition to related tools in daml

Can you elaborate why a button would be missing from the UI?  Is the Add-in not installed ?   If the Add-in is installed why would the button be missing?   I don't understand your use case for this.

Yes Addin not installed can be an only use case I can think of.

@GKmieliauskas  is quite correct as you need to implement your own states and conditions to control your Add-in's UI.   There is a ProGuide to states and conditions here:  ProGuide Code Your Own States and Conditions · Esri/arcgis-pro-sdk Wiki (github.com)

Then in your add-in's module class you can check for the existence of the needed Add-in using the FrameworkApplication API:

var theNeededModule = FrameworkApplication.FindModule("NeededModule");

The Module ID "NeededModule" can be found in the Add-in module's config.daml file:

...
  <modules>
    <insertModule id="NeededModule" className="Module1" autoLoad="false" ...>
 

If theNeededModule value is null the needed add-in is not available otherwise the needed add-in is available.  You can use that value to control your states and conditions.
