OK, Thank you..

This forum is for the WPF xamOutlookBar control. It sounds like you are using the Windows Forms UltraExplorerBar control in which case you should post your question in the forum for that control. Note, the same type of help page and string localization exists within our Windows Forms controls.

Thank you for your answer.

I have already red this post (I first made search in site before I posted my question).

I'm not sure this is what I need.

I tryed to use it, but it didn't succseed.

I don't have namespace "Window" under "Infragistics", but "Win".

so I tryed this:

Infragistics.Win.Resources.Customizer.SetCustomizedString("NavigationPaneMinimizedText", "Text when minimized");

but it didn't help.

Another point:

I want to replace the instruction, not the text when minimized.

the instruction I want to replace their text:

"Minimize the Navigation Pane", "MExpand the Navugation Pane", "click to Expand Navigaion Pane". (I want to set text in my language).

I would thank for your help,

Oshrat.
