11.2.3

11.2.3 - 2026-08-11

Improvements

• RadzenProgressBar and RadzenProgressBarCircular - new BufferValue parameter displays a secondary buffer indicator ahead of the primary value, e.g. for media buffering. Thanks to @pfs26!
• DialogService - the generic dialog methods now accept any type implementing IComponent instead of requiring ComponentBase. Thanks to @drewcav96!
• RadzenSpreadsheet - conditional formatting is now imported from and exported to XLSX files. Fixes #2645

Fixes

• RadzenSplitButton - the popup now opens reliably on Blazor Server even when the toggle is clicked right after the page loads. Clicks during the JS initialization round trip used to flip server state without showing the popup, leaving the button dead with aria-expanded="true". The popup is now driven entirely server-side and aria-expanded stays in sync when it is closed by clicking outside. Fixes #2650
• RadzenDatePicker - the popup no longer intermittently stops opening after rapid re-renders - a stale JS dispose could remove the freshly attached click handler. The trigger also works during initial page load on high-latency connections now that it no longer depends on JS handlers attached after render. Fixes #2646
• RadzenSecurityCode and RadzenSlider - keyboard and drag handlers are no longer removed by a stale JS dispose when the component re-renders rapidly.
• RadzenMenu - submenu clicks are handled by a static listener and now work immediately after page load, even before Blazor becomes interactive.
• Keyboard navigation - opening a popup with a key whose default action scrolls the page (ArrowDown on RadzenSplitButton, Space on RadzenDropDown, RadzenListBox, RadzenColorPicker and RadzenProfileMenu) no longer scrolls and instantly closes the popup on scrollable pages.
• RadzenDataGrid - client-side filtering is no longer applied to self-referencing hierarchies when LoadData is used. Fixes #2649
• RadzenChart - stacked series render significantly faster - compiled property getters are now cached instead of recompiled on every access.
• RadzenChat - mention search keeps working when the search text contains spaces while a mention is active. Thanks to @artnim!
• RadzenChat - keyboard navigation in the mention popup now works reliably - render-time preventDefault was replaced with a native keydown guard.
• RadzenSelectBar - background color is now correct in the Material, Default, Humanistic and Software themes.
• TooltipService - no longer modifies the caller's TooltipOptions instance, so shared options objects can be reused safely. Fixes #2641
