I am currently developing a Visual Studio extension. I want to have a button in the toolbox, this is created - but not enabled.
The main class of my extension is derived from AsyncPackage
. This is working fine Initialization is called on startup and everything I need is working.
Then I added a ToolWindow
, this will also create a new SettingsCommand
.
The auto created SettingsWindowCommand
is created by the main class. This is working and here the initialization is done without any error.
Still the command will be added greyed out and disabled.
Here is the initialization code:
public const int CommandId = 0x0100;
public static readonly Guid CommandSet = new Guid(GitHooksVSPackage.PackageGuidString); // currently taking the same GUID from the main class, before this was an extra GUID. Both versions did not work
public static async Task InitializeAsync(AsyncPackage package)
{
// Switch to the main thread - the call to AddCommand in SettingsWindowCommand's constructor requires
// the UI thread.
await ThreadHelper.JoinableTaskFactory.SwitchToMainThreadAsync(package.DisposalToken);
OleMenuCommandService commandService = await package.GetServiceAsync((typeof(IMenuCommandService))) as OleMenuCommandService;
Instance = new SettingsWindowCommand(package, commandService);
}
private SettingsWindowCommand(AsyncPackage package, OleMenuCommandService commandService)
{
this.package = package ?? throw new ArgumentNullException(nameof(package));
commandService = commandService ?? throw new ArgumentNullException(nameof(commandService));
var menuCommandID = new CommandID(CommandSet, CommandId);
var menuItem = new OleMenuCommand(this.Execute, menuCommandID);
commandService.AddCommand(menuItem);
Logger.Instance.WriteLine("Command added to CommandService.", LogLevel.DEBUG_MESSAGE);
}
Here is also the vsct

Any idea why the command is not enabled?
Thanks !
I don't know why this happens, I have tried to different things to force the command being enabled:
// this is called by the main class initializer
public static async Task InitializeAsync(AsyncPackage package)
{
// Switch to the main thread - the call to AddCommand in SettingsWindowCommand's constructor requires
// the UI thread.
await ThreadHelper.JoinableTaskFactory.SwitchToMainThreadAsync(package.DisposalToken);
OleMenuCommandService commandService = await package.GetServiceAsync((typeof(IMenuCommandService))) as OleMenuCommandService;
Instance = new SettingsWindowCommand(package, commandService);
}
private SettingsWindowCommand(AsyncPackage package, OleMenuCommandService commandService)
{
this.package = package ?? throw new ArgumentNullException(nameof(package));
commandService = commandService ?? throw new ArgumentNullException(nameof(commandService));
var menuCommandID = new CommandID(CommandSet, CommandId);
var menuItem = new OleMenuCommand(this.Execute, menuCommandID);
menuItem.BeforeQueryStatus += MenuItem_BeforeQueryStatus; // Add QueryStatus handler
menuItem.Enabled = true; // Ensure the command is enabled
commandService.AddCommand(menuItem);
Logger.Instance.WriteLine("Command added to CommandService.", LogLevel.DEBUG_MESSAGE);
}
private void MenuItem_BeforeQueryStatus(object sender, EventArgs e)
{
var command = sender as OleMenuCommand;
if (command != null)
{
command.Enabled = true; // Ensure the command is enabled
command.Visible = true; // Ensure the command is visible
}
}
Here none of these two approaches did help.
Please add/modify the following code in your .vsct
file:
<!-- Replace to your project name. -->
<Commands package="guidVSIXProject1Package">
xxx xxx
</Commands>
<Symbols>
<!-- This is the package guid. -->
<GuidSymbol name="guidVSIXProject1Package" value="{8de18409-91cd-46d3-af36-948c5c7bca1c}" />
</Symbols>
