The following code example creates a Chart with a handler for the DragOver event that displays a message box when a range of cells is dragged over the chart.

WithEvents DragOverChart As Microsoft.Office.Tools.Excel.Chart

Private Sub DisplayDragOver()
    Me.Range("A1", "A5").Value2 = 22
    Me.Range("B1", "B5").Value2 = 55

    DragOverChart = Me.Controls.AddChart(Me.Range("D2", "H12"), _
        "DragOverChart")
    DragOverChart.SetSourceData(Me.Range("A1", "B5"), _
        Excel.XlRowCol.xlColumns)
    DragOverChart.ChartType = Excel.XlChartType.xl3DColumn
End Sub 

Sub DragOverChart_DragOver() Handles DragOverChart.DragOver
    MsgBox("A range was dragged over the chart.")
End Sub
private void DisplayDragOver()
{
    this.Range["A1", "A5"].Value2 = 22;
    this.Range["B1", "B5"].Value2 = 55;

    Microsoft.Office.Tools.Excel.Chart chart1 =
        this.Controls.AddChart(this.Range["D2", "H12"], 
        "chart1");
    chart1.SetSourceData(this.Range["A1", "B5"], 
        Excel.XlRowCol.xlColumns);
    chart1.ChartType = Excel.XlChartType.xl3DColumn;

    chart1.DragOver +=
        new Excel.ChartEvents_DragOverEventHandler(
        chart1_DragOver);
}

void chart1_DragOver()
{
    MessageBox.Show("A range was dragged over the chart.");
