I am trying to build a UI similar to Beyond Compare when comparing 2 folders. It looks like you have a tree on the left and a second one on the right.

I am trying to have a UI similar to this with a single ultratree control.

I currently have set ViewStyle to OutlookExpress so I have my columns but would like to display the expansion in a second column.

Both columns are strings. So far, I don't need to have them editable.

With your new code, with the Show set to ShowExpansionIndicator.CheckOnDisplay, the nodes without the indicator appears completely left aligned.

Hi,

I tried this out, and it seems to work okay for me. I have attached an updated sample using CheckOnDisplay.

It is not working for me but I think I partly found why.

When I open your test solution (in VS2012), 2 references are wrong (as shown in 86212-references.png).

So I remove the reference to UIElementViewer as it doesn't seem to be required.

I replace the reference to the UltraWinTree with my local (also v12.2).

I run the solution and the children nodes are left aligned (as shown in 86212-rendering.png).

The issue might be that there are 2 versions on v12.2 as shown in 86212-references-code.png)! My version is 12.2.20122.2027 and yours seems to be 12.2.0.9000. Can it be the issue? Any fix for my (sub-)version?

Hi,

Ooooh, I see the problem, now. The references have nothing to do with it, I just misunderstood the problem. I thought you were talking about the indentation of the expansion indicators, but you meant the child rows. I misread it, sorry. I didn't even notice that part, so there was nothing in my sample to handle it.

Here's a new sample that works a lot better.

Thanks. It looks a lot better now.
