WPF: Shorten string to a specific lenght

Question

Hi everyone

I have a TreeView with a given width. When I add a node with a name which makes it exceed the maximal TreeView width it displays a vertical scrollbar.

I'd prefer to display only the beginning of the name followed by '...' to avoid the scrollbar. I tried googleing it but I fail to find a result.

Could someone tell me how it's done (Not the usage of Google, I mean the string shortening)?

Cheers AC

Answer 1

Typically like this:

<TextBlock Text="Whatever" TextTrimming="CharacterEllipsis"/>

However, you will need to incorporate this into your TreeViewItems by way of a template.

Answer 2

first you can set a MaxWidth on your treeview to avoid this vertical scrolling stuff. second, if you are actually adding a Tree item to your tree you can set the text, than register to the loaded event of the control, check his actual size and do the text modification.

but the most elegant thing you can do in my opinion is work with data binding and hie hierarchical data template and a converter that will trim the text for you(you can send the tree item to the converter)

hope this will help you
