please have a look at the attached screenshot of a FolderBrowser-Dialog . You see, that the button Make New Folder is not translated in german Language. It should be Neuer Ordner.
You will also see that the Cancel label does not have enough space and is cut off.
It would also look better to insert a space between the two buttons and the TreeView control above them.
And last but not least: how can I set the icon in the upper left corner of the dialog?
FolderBrowserDialogService uses the standard FolderBrowserDialog, and we cannot change its appearance. Instead, I suggest that you try our DXOpenFolderDialogService that supports DevExpress theming mechanism.
However, I noticed that in DXOpenFolderDialogService, the Cancel button's text is cropped as well, so I created the following report to address the issue: DXOpenFileDialog - The Cancel button's text is cropped. We'll update that ticket as soon as we have any news.
As for the dialog icon, it's inherited from its parent window. Thus, it's sufficient to specify the parent window's Icon property.
Let me know if you have additional questions.
