TPF UI Framework


  • Optimization in the theming framework - the result is faster loading time of applications that use any RadControl. This also speeds up VS designer loading time (with RadCotnrols)
  • RadCotnrols' ThemeChange handler is now thread safe
  • RadComboBoxElement cannot be added to any control in VS designer (e.g. in ribbonbar, toolstrip, etc)
  • HTML-like text formatting now supports spaces between words


  • RadControls for WinForms now uses MSI rather than EXE installation package
  • Important Note: For consistency among all product lines, we changed the way versions are displayed in the download section of our site with the release of Q3 2008. This was necessary, because in Q3 we introduced two new product lines, namely RadControls for Silverlight and Telerik OpenAccess ORM (bringing the number of our product lines to six) and we needed a better way of conveying the exact version that has been downloaded.

    The new file name convention is as follows:

    Downloaded file name: RadControls_for_WinForms_2008_3_1204_trial.msi

    "2008_3_1204" stand for Year.Release.Month.Date (YYYY.R.MDD), or the third release (Q3) in 2008, released on December 4th. Respectively, 2008_3_1105 means that this version was released on November 5th. Here is a quick reference table for your convenience:

    Release name File name DLL version
    Q3 2008 2008.3.1105
    Q3 2008 SP1 2008.3.1204
