How can I reproduce this issue?

I just build and run the app, and the issue comes up. I guess it can be reproduced when using details view and enabling checkboxes?

Because GridLength cannot convert to double implicitly, I thought this should be fixed sooner or later. 🤔

I think there is an existing converter that we can use.

I removed the binding, and merged Files.App.Converters and Files.App.ValueConverters namespace. I thought they were duplicated.

This is already being done in #11552

I also simplify some code in the converter classes. But I can restore it if necessary.

@Poker-sang thank you for your contribution, in general we prefer to limit the scope of PRs to the related issue/feature. As per the contribution guidelines, it's strongly recommended to open an issue and wait for an org member to approve it before opening the PR. This is more for the contributors benefit than ours because it helps everyone be on the same page and avoids duplicate work.
Files is a very active community project, so sticking to these guidelines helps keep track of which work is already in progress and which stuff still need to be picked up 🙂

I am sorry. I just encountered a XAML failure and tried to fix it. If this PR was duplicated, please close it. I will pay more attention to this from now on.

The data binding fix is good but the name spaces changes are being done in another PR.
