Hello Andrew,

thank you for your reply.

I think this code should answer your questions...

private void ultraToolbarsManager1_ToolValueChanged(object sender, Infragistics.Win.UltraWinToolbars.ToolEventArgs e)
{
if (e.Tool.Key == "IndexSelectionTemplateFilter")
{
var filterString = ((Infragistics.Win.UltraWinToolbars.TextBoxTool)e.Tool).Text.Trim().ToLower();

var popupTool = (Infragistics.Win.UltraWinToolbars.PopupMenuTool)this.ultraToolbarsManager1.Tools["IndexSelectionTemplates"];

var templateTools = popupTool.Tools.OfType<Infragistics.Win.UltraWinToolbars.ButtonTool>().Where(p => p.Key.StartsWith(this.selectionTempalteToolKeyPrefix)).ToArray();

foreach (var templateTool in templateTools)
{
templateTool.SharedProps.Visible = (filterString == string.Empty || templateTool.SharedProps.Caption.ToLower().Contains(filterString));
}
}
}

Here we are reacting to the ValueChangedEvent from the TextBoxTool (this filter) and apply the visible state to the MenuItems (ButtonTools).

The filter and the ButtonTools are on the same level and popped out in this moment. Like this....

- FilterTool

- ButtonTool1

- ButtonTool2

- ,,,

When chaning the filter the visibility of the ButtonTool1-n is changed.

Ot to be more specific: The TextBoxTool is part of popupTool.Tools too.
