Additional context

this could totally be an issue on XAML Control Gallery's side so sorry.

This does seem to be a control issue, but it could be confusing to show as an I-beam if clicking doesn't place the caret at that location. On the other hand it would be nice to help differentiate between editable and non-editable comboboxes.

I also updated the title to reflect this, I hope that's ok @poopooracoocoo :)

@jevansaks When I hover over the text box in Word it is a text select pointer and selects all of the text when clicked instead of placing a carat.

OneNote UWP does the same thing. Text cursor, clicking selects all text.

[jevansaks]

Good observations @poopooracoocoo @mdtauk! Seems like we should just update this control to show the text cursor and not change anything else.

Thanks for jumping on this, @jevansaks!

Hi, @Poopooracoocoo and @mdtauk, I'll be carrying this issue forward. I agree with @jevansaks. We should differentiate between an editable and non-editable ComboBox. However, the "select all text" behavior is an intentional quick-action feature as most often users bring their focus to these controls to fully clear and replace the contents than to edit the existing contents.

I will convert this ticket to a bug so that we can start acting on a fix for the cursor. If the "place caret" behavior is still desired, please let me know and we can kick off a discussion for that and the scope of impact it would need to have, if implemented, to deliver consistency across our control set.

How does this sound to everyone?

I would vote for a Place Caret on _single click_ option, but a _Double Click_ to Select could be useful.

The Edge/Chrome URL bar, will select all on _single click_, and _another single click_ will place the Caret - but _double clicking_ will select a word or part of the text.

The UWP Text field currently Places the Caret on _Single Click_, Selects a word or part of the text on _Double Click_, and Selects all on a _Triple Click_

Whatever the behaviour chosen, it should apply to future editable controls like NumberBox, Editable Time and Date Pickers, etc

Perfect. I see @Poopooracoocoo has updated this issue for the bug path.

Whatever the behaviour chosen, it should apply to future editable controls like NumberBox, Editable Time and Date Pickers, etc.

@mdtauk I hear you and this is something I can get behind. Is this already being covered by any of your design discussions/proposals or should I open up a dedicated issue?

[mdtauk]

@SavoySchuler I don't think I have included any cursor behaviour in my mockups, but I have covered editable vs non-editable control designs in #899

[Poopooracoocoo]

@mdtauk off topic but do you work at MS?

No :)

@Poopooracoocoo I checked in with @jevansaks, our engineering manager, and the fix to this bug will require WinUI 3.0. @jevansaks labeled as such, so I will unassign myself for now, and we'll be back to this when WinUI 3.0 is here. 😄 Thanks for filing this, you're awesome!

@mdtauk, thanks! I have it in my to-do list to add a proposal for this topic. Please feel encourage to beat me to it, but otherwise I will tag you when I have it up!

[mdtauk]

@SavoySchuler I shall leave that honour to yourself. I was only stating the current behaviours - which one becomes a default is for greater minds than mine.

[SavoySchuler]

No need to undersell yourself, @mdtauk! But sounds great, I have it on my list. 😊

[Poopooracoocoo]

@SavoySchuler Hey do you have any idea on when you guys will be working on new features for WinUI? WinUI 3.0 development is almost finished I think.
