    Hi Team,


    I have changed the backcolor of the tooltip with below code but it is not working,


    RadToolTip toolTip = new RadToolTip();
    toolTip.IsBalloon = true;
    toolTip.BackColor = Color.LightSkyBlue;
    toolTip.SetToolTip(this.button1, "Telerik test");

    Hello Amal, 

    Thank you for writing.  

    RadToolTip is a derivative of the MS ToolTip. The following StackOverflow thread demonstrates a sample approach how to customize the BackColor: http://stackoverflow.com/questions/12990757/change-winform-tooltip-backcolor

    Here is a sample code snippet: 
    public RadForm1()
        this.radButton1.ShowItemToolTips = true;
        this.radButton1.ToolTipTextNeeded += radButton1_ToolTipTextNeeded;
    private void radButton1_ToolTipTextNeeded(object sender, ToolTipTextNeededEventArgs e)
        e.ToolTip.BackColor = Color.Yellow;
        e.ToolTip.ForeColor = Color.Red;
        e.ToolTipText = "Telerik button";
        e.ToolTip.OwnerDraw = true;
        e.ToolTip.Draw += ToolTip_Draw;
    private void ToolTip_Draw(object sender, DrawToolTipEventArgs e)
        ToolTip toolTip = sender as ToolTip;
        e.Graphics.FillRectangle(new SolidBrush(toolTip.BackColor), e.Bounds);

    I hope this information helps. Should you have further questions I would be glad to help.
