+## Description
+
+This article shows how to identify a datapoint of a RadBarSeries in RadChartView when clicking on a specific bar. 
+
+## Solution
+
+To achieve this, handle the `MouseClick` event of RadChartView and use the `HitTest` method to detect the datapoint associated with the clicked bar. 
+Here is the code example:
+
+````C#
+this.radChartView1.MouseClick += RadChartView1_MouseClick;
+
+private void RadChartView1_MouseClick(object sender, MouseEventArgs e)
+{
+    foreach (var s in this.radChartView1.Series)
+    {
+        Telerik.WinControls.UI.BarSeries barSeries = s as Telerik.WinControls.UI.BarSeries;
+        if (barSeries != null)
+        {
+            DataPoint dp = barSeries.HitTest(e.Location.X, e.Location.Y);
+            if (dp != null)
+            {
+                Console.WriteLine(dp.Label); // Outputs the datapoint label
+            }
+        }
+    }
+}
+
+```
