Display the inspector for the specified model

To display the inspector for the specified model, use the SetInspectedObject method of the IWorkspaceState object. To deselect the inspector (to display a message in the inspector indicating that the target element should be selected), specify null as the argument.

public void SetInspectedObject(ICommandContext c, ICommandParams p)
{
    var model = c.App.Workspace.CurrentProject.GetAllChildren().FirstOrDefault(m => m.Name == "ADAS System Requirements");
    IWorkspaceState workspaceState = c.App.Workspace.State;

    //Set the specified model as the inspector
    //If null is specified, the inspector will be deselected
    workspaceState.SetInspectedObject(model);
}
