Custom Ribbon Button Drop Down in Add-in

[JoeMadrigal]

I'm looking to create my own custom menu from a button drop down like the "Download Map" on the standard Pro Map tab:

Is there a way to do this in the Pro SDK?  Perhaps using a supplied XAML template inside a button splitter or palette control?  I looked through the samples and don't seem to find anything. Maybe its not possible?

Did you try putting a CustomControl inside a SplitButton?

See page 6 here:

Haven't tried that yet since there is little documentation on custom controls that I can see.  I just added the custom control to my project now.  I just have to figure out how to add it to the split button (I assume in place of any of the buttons perhaps?).  Thanks for the presentation.  Just wish I can see their demos for the details 🙂

Yeah, the documentation is pretty sparse.  This works for me, but when I check/uncheck the checkbox on my control, it closes.  With Esri's download map control, it stays open when do the same.

Ahh, seems straight forward now.  Appreciate it!

Checkbox issue might be frustrating, I'll play with it.

looking in the ADMapping.daml I see this:

<customControl id="esri_mapping_downloadMap" caption="Download Map" className="ArcGIS.Desktop.Internal.Mapping.Ribbon.DownloadMap" disableIfBusy="true" showHelp="true" staysOpenOnClick="true" isDropDown="true"
                      ...>
          <content className="ArcGIS.Desktop.Internal.Mapping.Ribbon.DownloadMapControl" />
          ...
</customControl>

Note the staysOpenOnClick and IsDropDown attributes. I think those are what you are after.

You can find the ADMapping.daml here: <your Pro install location>/bin/Extensions/Mapping

and here: https://github.com/Esri/arcgis-pro-sdk/wiki/DAML-ID-Reference-ADMapping.daml

Ok, this is what I learned.  If I host the custom control via splitbutton, then the staysOpenOnClick has no affect.  If I put the custom control directly in the tab group, then it works as long as you also set the isDropDown to true.  Thanks @CharlesMacleod  for the hint and link.  This is exactly what they are doing in the download map custom control!
