How to use Editor.SetImpliedSelection

I have tried a few examples found on the forum and on the documentation, but I was never able to set the selection at the end of the command.

Below is a simple test that is supposed to keep selected only the first pre-selected entity.

You can test it by selecting a few entities and running the command. After the the command exits, only the first pre-selected entity should be selected. Instead nothing is selected.

[CommandMethod("TestRemoveItemFromPreselection", CommandFlags.UsePickSet)]
public void TestRemoveItemFromPreselection()
{
    var ed = Application.DocumentManager.MdiActiveDocument.Editor;
    var selectionResult = ed.SelectImplied();
    if (selectionResult.Status != PromptStatus.OK)
    {
        ed.WriteMessage($"selectionResult.Status: {selectionResult.Status}");
        return;
    }
    var selectionSet = selectionResult.Value;
    var ids = new ObjectIdCollection(selectionSet.GetObjectIds());
    var ids2 = new ObjectId[1];
    ids2[0] = ids[0];
    ed.SetImpliedSelection(ids2);
}

Hi,

You have to add the CommandFlags.Redraw.

[CommandMethod("TestRemoveItemFromPreselection", CommandFlags.UsePickSet | CommandFlags.Redraw)] public void TestRemoveItemFromPreselection() { var ed = Application.DocumentManager.MdiActiveDocument.Editor; var selectionResult = ed.SelectImplied(); if (selectionResult.Status != PromptStatus.OK) { ed.WriteMessage($"selectionResult.Status: {selectionResult.Status}"); return; } var ids2 = new[] { selectionResult.Value.GetObjectIds()[0] }; ed.SetImpliedSelection(ids2); }
