Hello again, I have a problem showing information in TooltipsAppearance tags, inside clientTemplate.
On line 18, I have tried the following ways:
Valor: #=dataItem.Porcentaje#
Valor: #:dataItem.Porcentaje#
Valor: #=series.Porcentaje#
Valor: #:series.Porcentaje#
And I just get to show "undefined"
Somebody could help me? Thanks
The HTML code:

Hi Arturo,
Both of the "dataItem" options can be used for accessing the value of a databound chart, including the "value" field itself. I am attaching a page with some sample data bound to the chart where the tooltip values are accessed properly, so you can examine it and compare it with your actual setup at your end.
I am using the latest 2020.2 512 version of the controls.

Hi Vessy, it works when I changed the way to set the datasource, this was my code:
For Each fila As DataRow In dtSols.Rows
serieItem = New SeriesItem
serieItem.Name = fila("TipoSol").ToString
serieItem.YValue = fila("Porcentaje").ToString
rChartSolXTipo.PlotArea.Series(0).Items.Add(serieItem)
Next
Now I use:
rChartSolXTipo.DataSource = daoSols.GetTable()
rChartSolXTipo.DataBind()
Thanks!!!
