    RadControls version v2012.3.1211.40
    .NET version v4.0
    Visual Studio version vs 2012
    programming language C#
    browser support N/A

    Incapsulate ScreenTips in one location and closely follows Office 2007 Screen Tip popup convention/style.

    In your project, create a new class called ExtensionMethods and paste the following:
    If you already have a class ExtensionMethods, just paste the #region SCREENTIP but make sure the 2 using Telerik... are in the class.

    using System;
    using System.Drawing;
    using System.Linq;
    using System.Windows.Forms;
    using Telerik.WinControls;
    using Telerik.WinControls.UI;
    namespace ExtensionMethods
        public static class MyExtensions
            #region ////////// SCREENTIP ... ///////////////
            /* TO USE, in your form or user control add a reference to this namespace (using ExtensionMethods;)
                void btn_ScreenTipNeeded(object sender, Telerik.WinControls.ScreenTipNeededEventArgs e)
                    e.Item.PopupTip(e, "Format Painter (Ctrl+Shift+C)", null, "<html>Copy <b>formatting</b> from one place and apply it to another.");
            private static RadOffice2007ScreenTipElement screenTip = new RadOffice2007ScreenTipElement();
            /// <summary>
            /// Set to true to display or hide all PopupTips.
            /// </summary>
            public static bool ShowPopupTips = true;
            /// <summary>
            /// Incapsulate ScreenTips in one location and closely follows Office 2007 Screen Tip popup convention/style.
            /// </summary>
            /// <param name="control"></param>
            /// <param name="e">ScreenTipNeededEventArgs to allow a global (one location) config of Delay and Offset.</param>
            /// <param name="titleText">Caption. Leave blank to hide the caption area.</param>
            /// <param name="mainImage">Image shown middle-left of main text area or null if no image to display.</param>
            /// <param name="mainText">Main text area. If the mainImage is null and mainText is empty, the main area is hidden.</param>
            /// <param name="showFooter">Show/hide footer. Default is show it.</param>
            public static void PopupTip(this RadItem control, ScreenTipNeededEventArgs e, string titleText, Image mainImage = null, string mainText = "", bool showFooter = true)
                if (!ShowPopupTips)
                e.Delay = 1;
                e.Offset = new System.Drawing.Size(-32, 0);
                screenTip = null;
                screenTip = new RadOffice2007ScreenTipElement();
                screenTip.CaptionLabel.Padding = new Padding(8, 8, 8, 2);
                screenTip.CaptionLabel.Font = new Font("Tahoma", 8.5f, FontStyle.Bold);
                screenTip.CaptionLabel.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighQuality;
                screenTip.CaptionLabel.Opacity = .8;
                //screenTip.CaptionLabel.TextImageRelation = TextImageRelation.ImageBeforeText;
                screenTip.CaptionLabel.TextAlignment = ContentAlignment.MiddleLeft;
                //screenTip.CaptionLabel.ImageAlignment = ContentAlignment.MiddleLeft;
                //screenTip.CaptionLabel.Image = myNamespace.Properties.Resources.help16;
                if (string.IsNullOrEmpty(titleText))
                    screenTip.CaptionLabel.Visibility = ElementVisibility.Hidden;
                    screenTip.CaptionLabel.Text = titleText;
                screenTip.MainTextLabel.Padding = new Padding(8, 0, 8, 0);
                screenTip.MainTextLabel.Font = new Font("Tahoma", 8.5f);
                screenTip.MainTextLabel.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.AntiAlias;
                screenTip.MainTextLabel.Opacity = .9;
                screenTip.MainTextLabel.TextImageRelation = TextImageRelation.ImageBeforeText;
                screenTip.MainTextLabel.TextAlignment = ContentAlignment.MiddleLeft;
                screenTip.MainTextLabel.ImageAlignment = ContentAlignment.MiddleLeft;
                if (string.IsNullOrEmpty(mainText) && mainImage == null)
                    screenTip.MainTextLabel.Visibility = ElementVisibility.Hidden;
                screenTip.MainTextLabel.Image = mainImage;
                if (!string.IsNullOrEmpty(mainText))
                    screenTip.MainTextLabel.Text = mainText;
                screenTip.FooterVisible = showFooter;
                screenTip.FooterLine.Visibility = showFooter ? ElementVisibility.Visible : ElementVisibility.Hidden;
                screenTip.FooterTextLabel.Padding = new Padding(8);
                screenTip.FooterTextLabel.Font = new Font("Tahoma", 8.5f, FontStyle.Bold);
                screenTip.FooterTextLabel.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.AntiAlias;
                screenTip.FooterTextLabel.Opacity = .8;
                screenTip.FooterTextLabel.TextImageRelation = TextImageRelation.ImageBeforeText;
                screenTip.FooterTextLabel.TextAlignment = ContentAlignment.MiddleLeft;
                screenTip.FooterTextLabel.ImageAlignment = ContentAlignment.MiddleLeft;
                screenTip.FooterTextLabel.Image = SystemIcons.Question.ToBitmap().GetThumbnailImage(22, 22, null, IntPtr.Zero); //myNamespace.Properties.Resources.help16;
                screenTip.FooterTextLabel.Text = "  Press F1 for more help.";
                //The following line indicates that Office 2007 UI complient screen tip sizing should not be used.
                screenTip.EnableCustomSize = false;
                screenTip.AutoSizeMode = RadAutoSizeMode.Auto;
                control.ScreenTip = screenTip;
            #endregion //////// END SCREENTIP ////////////////

    In your forms and user controls, add the reference to your Extension Methods Namespace:
    using ExtensionMethods;

    Add the event handler of your RadControl to your form:
    protected override void OnLoad(EventArgs e)
        btn.ScreenTipNeeded += btn_ScreenTipNeeded;

    Call the screen tip from the event:
    void btn_ScreenTipNeeded(object sender, Telerik.WinControls.ScreenTipNeededEventArgs e)
        e.Item.PopupTip(e, "Format Painter (Ctrl+Shift+C)", null
    , "<html>Copy <b>formatting</b> from one place and apply it to another.");
