Мore Enhancements Across the Suite

Тhis release introduces several targeted improvements across WinForms controls, adding greater consistency, control and flexibility in common scenarios. 

  • VirtualGrid – New Sorting Mode 
    A new sorting mode ensures columns always remain sortable by removing the option for a “no sort” state, helping enforce consistent and predictable user experience patterns. 

  • RadPictureBox – Extended ImageLoaded Information 
    The ImageLoaded event now exposes additional details such as file path and image type, making it easier to trace image sources or implement auditing and diagnostics logic. 

  • RadStepProgressBar – StepClicked Event 
    A new StepClicked event provides more granular control over user interactions, enabling custom navigation, validation flows or workflow logic. 

  • RadMap – Support for Transparent Images 
    Transparent images are now fully supported and render correctly on the map surface, improving the visual quality of icons, overlays and custom markers. 

These enhancements extend control and polish across the WinForms suite, addressing both usability and customization needs.
