Hi pratik mehta,

You can achieve the desired functionality like this (note that it is essential to cast the ChartLegend to its base ItemsControl class in order to retrieve the legend items due to the specifics of the control implementation):

public MainPage()
{
    InitializeComponent();
 
    RadChart1.DataBound += this.RadChart1_DataBound;
    RadChart1.ItemsSource = new int[] { 1, 2, 3 };
}
 
private void RadChart1_DataBound(object sender, ChartDataBoundEventArgs e)
{
    foreach (ChartLegendItem legendItem in (RadChart1.DefaultView.ChartLegend as System.Windows.Controls.ItemsControl).Items)
    {
        legendItem.Tag = "TEST";
    }
}

Hope this helps.


Best wishes,
