What does Hide do?

What does the Hide option in a pane's header menu do?

I know the default behavior of a pane is to hide when closed, rather than actually removing the pane. Is this what the Hide option does? If so, I would think that "Close" would be a more appropriate term, to match the tool tip on the X button. The user does not care what happens behind the scenes.

Is it possible to remove this option from a pane's header menu?

Well the Header of the menu item is a resource string so you could compare the header to that resource string as well. e.g.

private void dockManager_OptionsMenuOpening(object sender, PaneOptionsMenuOpeningEventArgs e)

{

string hideText = Infragistics.Windows.DockManager.Resources.GetString("HidePaneMenuItem");

for(int i = e.Items.Count - 1; i >= 0; i--)

{

MenuItem mi = e.Items[i] as MenuItem;

if (mi != null && mi.Command == ContentPaneCommands.Close)

{

if (object.Equals(hideText, mi.Header))

{

e.Items.RemoveAt(i);

}

}

}

// now if we removed an item there may be a separator at the end/beginning

// or two in a row so clean up those

RemoveUnneededSeparators(e.Items);

}

private static void RemoveUnneededSeparators(System.Collections.IList items)

{

int lastSeparator = int.MaxValue;

// remove unneeded consecutive separators

for (int i = items.Count - 1; i >= 0; i--)

{

if (items[i] is Separator)

{

if (lastSeparator == i + 1)

items.RemoveAt(i);

lastSeparator = i;

}

}

// remove separator at the beginning

if (items.Count > 0 && items[0] is Separator)

items.RemoveAt(0);

// remove separator at the end

if (items.Count > 0 && items[items.Count - 1] is Separator)

items.RemoveAt(items.Count - 1);

}

Hello Andrew,

I am trying your suggestion, but encountered the problem in which some panes have both Close and Hide and they both seem to be related to the same command and have the same name. I would like to always take hide out and leave close when applicable. What would be the best way that you would recommend.

Thanks

Hiding invokes the Close command. The text displayed to the end user is consistent with what you see in VS. You can change the text if you wish using the ResourceCustomizer. If you want to remove the menu item then you can look at handling the OptionsMenuOpening of the ContentPane and look for a menu item whose command is ContentPaneCommands.Close. Note if you remove menu items then you may also need to add code to remove any unneeded separators.
