This repository contains curated WPF examples demonstrating features and customization patterns for the SfTextBoxExt autocomplete control.

Overview - The samples show how to integrate SfTextBoxExt into desktop applications and illustrate common scenarios such as autocomplete suggestions, custom item templates, filtering strategies, selection behavior, and styling.

Samples - The Samples/ folder includes the following example projects (each is a standalone WPF project with a MainWindow):

  • AutoComplete-and-filtering: Demonstrates suggestion sources and filtering behavior (prefix, substring, etc.).
  • Diacritic-sensitivity: Shows handling of diacritic-insensitive matching and culture-sensitive filtering.
  • Dropdown-customization: Customizes suggestion dropdown appearance and item templates.
  • Getting-Started: Minimal integration example to quickly see SfTextBoxExt in action.
  • ImageMemberPath: Example of showing images/icons alongside suggestion items.
  • Multipath_Search: Contains a solution (Multipath_Search.sln) demonstrating multipath search scenarios.
  • Single-and-multiple-selection: Illustrates single-selection and multi-selection modes.
  • Textbox-customization: Styling and behavior customizations for the textbox control.
  • TextHighlightMode: Demonstrates different highlight strategies for matched text.

Getting started -

  1. Open the solution or an individual project in Visual Studio 2026.
  2. Restore NuGet packages and build the project. If needed, restore packages from the command line:
nuget restore "Multipath_Search.sln"

Or open the project in Visual Studio and let it restore packages automatically (projects use packages.config).

  1. Run a sample project (press F5 or run the project from Visual Studio). Each sample's MainWindow demonstrates the specific feature.

Notes & best practices -

  • Keep suggestion lists small or use virtualization for good responsiveness.
  • Use asynchronous data loading for large or remote datasets.
  • Customize item templates to show icons or detail lines for better UX.
