How to show value in Tooltip of ColumnSeries?

[Saqib]

Hi,
I m having hard time to display value in tooltip field of column series. Anytime I tried to set value, I always see Y value in tooltip.
See below the way I m adding series and tried to modify tooltip value.

For Each r As DataRow In ds2.Tables(0).Rows
    Dim item As New SeriesItem
    Dim name As String = r.Item("FVID")
    Dim vol As Integer = r.Item("total")

    item.Name = name
    item.YValue = vol
    item.TooltipValue = name    <-- NOT WORKING

    barChartSeries.Items.Add(item)

    Dim xaxis As New AxisItem(name)
    BarChart.PlotArea.XAxis.Items.Add(xaxis)
Next

Hi Saqib,

The TooltipValue property is available only for the BubbleSeries. If you want to display custom values in the tooltips you must bind the chart and use templates. More information on the matter is available in this online demo and the following set of articles:

• Overview
• Using ClientTemplates to Display HTML and Execute JavaScript
• Shared Template for ToolTips

SInce I have converted my chart code to use databind; now how would I color different each item in SeriesItem?

Hi Saqib,

For a databound chart you can use the ColorField property exposed by each series. Such an example is illustrated in this online demo.
