## Summary of the Pull Request Prevents users from clearing the name field in ImageResizer size preset edit dialog. Empty names made the UI confusing without causing errors. ## PR Checklist - [ ] **Communication:** I've discussed this with core contributors already.

This matches the existing pattern used for `FileName` validation in `ImageResizerViewModel`. TwoWay binding in UI causes the TextBox to revert when users attempt to clear the field—standard behavior for required fields. ## Validation Steps Performed - Added unit test `ImageSizeNameShouldNotBeSetToEmptyOrNull()` covering all rejection and acceptance cases - Verified silent rejection behavior matches `FileName` property pattern > [!WARNING] > > <details> > <summary>Firewall rules blocked me from connecting to one or more addresses (expand for details)</summary> > > #### I tried to connect to the following addresses, but was blocked by firewall rules: > > - `i1qvsblobprodcus353.vsblob.vsassets.io` > - Triggering command: `/usr/bin/dotnet dotnet build /home/REDACTED/work/PowerToys/PowerToys/src/modules/cmdpal/ext/Microsoft.CmdPal.Ext.Registry/Helpers/ResultHelper.cs /home/REDACTED/work/PowerToys/PowerToys/src/modules/cmdpal/ext/Microsoft.CmdPal.Ext.Registry/Helpers/RegistryHelper.cs /home/REDACTED/work/PowerToys/PowerToys/src/modules/cmdpal/ext/Microsoft.CmdPal.Ext.Registry/Enumerations/TruncateSide.cs /home/REDACTED/work/PowerToys/PowerToys/src/modules/cmdpal/ext/Microsoft.CmdPal.Ext.Registry/Constants/KeyName.cs /home/REDACTED/work/PowerToys/PowerToys/src/modules/cmdpal/ext/Microsoft.CmdPal.Ext.Registry/Constants/MaxTextLength.cs /home/REDACTED/work/PowerToys/PowerToys/src/modules/cmdpal/ext/Microsoft.CmdPal.Ext.Registry/Commands/CopyRegistryInfoCommand.cs /home/REDACTED/work/PowerToys/PowerToys/src/modules/cmdpal/ext/Microsoft.CmdPal.Ext.Registry/Commands/OpenKeyInEditorCommand.cs /home/REDACTED/work/PowerToys/PowerToys/src/modules/cmdpal/ext/Microsoft.CmdPal.Ext.Re /home/REDACTED/work/PowerToys/PowerToys/src/modules/cmdpal/ext/Microsoft.CmdPal.Ext.Registry/CopyType.cs /home/REDACTED/work/PowerToys/PowerToys/src/modules/cmdpal/ext/Microsoft.CmdPal.Ext.Registry/Icons.cs` (dns block) > > If you need me to access, download, or install something from one of these locations, you can either: > > - Configure [Actions setup steps](https://gh.io/copilot/actions-setup-steps) to set up my environment, which run before the firewall is enabled > - Add the appropriate URLs or hosts to the custom allowlist in this repository's [Copilot coding agent settings](https://github.com/microsoft/PowerToys/settings/copilot/coding_agent) (admins only) > > </details> <!-- START COPILOT ORIGINAL PROMPT --> <details> <summary>Original prompt</summary> > > ---- > > *This section details on the original issue you should resolve* > > <issue_title>[Settings: ImageResizer] Edit size dialog: Add validation against empty name</issue_title> > <issue_description>There is one small thing we should add.
