show duplicate columns values on Tooltip UltraChart
posted

Hello,

I have a table with 3 column: Date, Count, SigCount. I want to show the SigCount value just in the tooltip.

Here is the code:

                dataChart.DataSource = table.DefaultView;
                dataChart.Data.excludedColumns.Clear();
                dataChart.Data.excludedColumns.Add(2);
                dataChart.DataBind();
                dataChart.Axis.X.Labels.SeriesLabels.Visible = true;
                dataChart.Axis.X.Labels.Visible = true;
                dataChart.Axis.X.Labels.ItemFormatString = "<SERIES_LABEL" + format + ">";

                dataChart.Tooltips.Format = TooltipStyle.Custom;
                dataChart.Tooltips.FormatString =    What to put here?

    Hi Hani,

    Thank you for contacting Infragistics Developer Support.

    I assume you want to show values from a field in your data table in the chart tooltip. In order to do that you can use the IRenderLabel interface. With these interface you can create custom tooltips for your chart. You need to create a class which implements this interface and pass to this class the data table. Then in the ToString method of the interface, return the value from the corresponding row in your table. You can get the row by using the “DATA_ROW” value of the hash table that is the argument in the ToString method.

    I have attached a sample which demonstrates this suggestion.

    Please let me know if you have any additional questions.
