Pull request overview
This PR fixes a visual truncation issue in the Color Picker editor where long color format names like "DECIMAL" and "HEX Int" were being cut off, causing them to display incorrectly (e.g., "DECIMAI" instead of "DECIMAL").
Key Changes
- Increased the first column width in
ColorFormatControl.xamlfrom 48px to 64px to accommodate the longest format names (7 characters) - The change maintains proper text truncation via the existing
TextTrimming="CharacterEllipsis"property for custom format names that may exceed the new width

Summary of the Pull Request
Fixes #25063 - Long color format names are cut off in the Color Picker editor, causing names like "DECIMAL" to appear as "DECIMAI".
PR Checklist
Detailed Description of the Pull Request / Additional comments
The first column width in
ColorFormatControl.xamlwas set to a fixed 48 pixels, which is too narrow to display longer format names like:This caused the last character(s) to be clipped, making "DECIMAL" appear as "DECIMAI" as shown in the issue.
Solution
Increased the column width from 48px to 64px. This provides enough space to display all current format names while maintaining the existing layout proportions.
The
TextTrimming="CharacterEllipsis"is already set on theFormatNameTextBlock, so any custom format names that exceed the new width will be properly truncated with "..." instead of being cut off abruptly.Before
After
The format name "DECIMAL" should now display correctly without being cut off.
