Can't get there with DockPane. Have to use Pane. Not much documentation on Pane but if you add a new Pane item the boilerplate code does a lot for you.
For me the boilerplate CustomPaneClassName.Create() places the pane in whatever pane is active.
So to work around we did a little slight-of-hand/old-school-jank coding:
- Activate ArcPro’s built-in Attribute Table immediately before loading our custom Pane.
- This will activate the Pane referenced in your screenshot.
- Load our custom pane.
- There is no option for where to open it.
- It will open in the Active pane because of step 1.
- Close the ArcPro Attribute Table.
Surprisingly I couldn't tell the ArcPro Attribute Table opened and closed. Happens quickly enough it appears to simply open my custom pane and no others. It also could be the case that my warm work laptop's latency helped make it appear magic.
Here's the admittedly silly code:
// validate map view
if (MapView.Active is null) return;
// get map ref and validate
var map = MapView.Active.Map;
if (map.MapType != MapType.Map) return;
// validate map layers
if (map.Layers.Count() > 0) {
// first layer of TOC as placeholder and validate it can load to table content
var placeholderLayerMapMember = map.Layers.First() as MapMember;
// validate. If you use other layers, still recommend mapmember validation
if (FrameworkApplication.Panes.CanOpenTablePane(placeholderLayerMapMember)) {
// get ArcPros built-in Edit Attributes table pane in order to open the pane below the map. Otherwise could open in map tab
var standardEditPane = FrameworkApplication.Panes.OpenTablePane(placeholderLayerMapMember) as Pane;
// build my custom pane and open in active pane
var pane = MyCustomPaneViewModel.Create();
// opened my custom pane so can close ArcPros Edit Attributes table pane. Unecissary if you want ArcPros Edit Attributes table to stay open
// open in parallel pane tab, but closing gives the illusion that only my custom pane opened
standardEditPane.Close();
// validate pane
if (pane is null) return;
// ... do things with my custom pane
}
}
