Proposal: Prefix and Suffix Properties for TextBox #784
Description
Proposal: Prefix and Suffix properties for TextBox
Summary
These would be templated and stylable content properties for the TextBox control and any controls deriving from it. They would add context to the text being entered, and enable easy formatting of things like URLs, currencies, and units and well as Xaml content such as icons, buttons, ComboBox, etc.
Rationale
During discussion, planning and spec writing for the NumberBox control #483
https://github.com/microsoft/microsoft-ui-xaml-specs/pull/29
One of the features that received a lot of support was the addition of Prefix and Suffix content - which is a feature taken from the Fabric Web TextField control.
Because of the useful-ness of this feature, it was suggested that this feature should make its way to the TextBox itself, and could then be available for NumberBox and other similar controls in the future.
Scope
| Capability | Priority |
|---|---|
| Display content within the TextBox before and/or after the Text string | Must |
| Provide default styling for Buttons or ComboBoxes added as content to match the UX | Must |
| The ability to edit the template and/or style of the Prefix and Suffix | Must |
| The ability to append the content to text that is copy and pasted | Could |
| API | Priority |
|---|---|
| Display/Hide Prefix and Suffix. | Must |
Important Notes
Here are some visual examples of how these properties could look on the TextBox:
The look for these Prefix and Suffix content is taken from the FabricWeb controls, but using the XAML control metrics.
Notes
- Note that this concept already exists in Fabric Web. Alignment of design and APIs where able is ideal.
