    I have drawn a Bar chart with Date on X-axis and number(0-120) on Y-axis.

    I have a combo box with list of dates which i have used in the bar chart.

    if i select a single date/ Multiple dates in comboBox , then i need to highlight (Or) change the color of  the particular date(s) DataItem(s) Bar(s) in the chart.

    is there any way to do this? If so please share sample code.

    Help is highly appreciated.

    Thanks and Regards,

    Hello chandra,

    You can modify the appearance of each item, after its creation, either through design-time, data-binding, or by code. Here is a sample code:
    1 protected override void OnLoad(EventArgs e) 
    3     base.OnLoad(e); 
    5     InitChartItems(); 
    7     this.radChart1.Series[0].Items[0].Appearance.FillStyle.MainColor = Color.Red; 
    8     this.radChart1.Series[0].Items[0].Appearance.FillStyle.SecondColor = Color.DarkRed; 
    9     this.radChart1.Series[0].Items[0].Appearance.Border.Visible = false
