Custom colored text in TreeView and GridView

[Josef Nemec]

I need to have TreeView and GridView with text that can be colored with multiple colors. In practice I need to color some specific words, it should look like this:

How would I do that in Eto? I know there's DrawableCell for GridView, but I don't see anything like that for TreeView.

Hi Josef,

I'd suggest to use the TreeGridView, which supports using DrawableCell (and multiple columns).

Hope this helps!

Thanks, TreeGridView seems to work ok. However I'm currently struggling with DrawableCell. I don't known how to make sure that it resizes GridColumn based on how long the text is. I can measure text size via MeasureString method, but I don't know how to update Column width from Paint event handler.

I have a similar need and following Curtis advise I can now successfully use TreeGridView and DrawableCell, 

Unfortunately I have not managed so far to make a DrawableCell work if it is the first one in the Columns list: it is always rendered all white. 

Any clue why?

Little update at my last comment: DrawableCell as a first column works fine on Mac but is always rendered all white on Windows using Wpf

Hi Massimiliano,

This sounds like a bug.  You should enter an issue on https://github.com/picoe/Eto/issues and someone can take a look.

Cheers!
