Hi

I found solution thrue convertor.

I create datatemplate for ToolTip

<local:SeriesConverter x:Key="seriesConverter" />
<DataTemplate x:Key="ToolTipTemplate">
<StackPanel>
<StackPanel Orientation="Horizontal">
<TextBlock Text="Název: " FontWeight="Bold"/>
<TextBlock Text="{Binding Path=., Converter={StaticResource seriesConverter}, ConverterParameter=FragmentNazev}" />
</StackPanel>
<StackPanel Orientation="Horizontal">
<TextBlock Text="Období: " FontWeight="Bold"/>
<TextBlock Text="{Binding Path=., Converter={StaticResource seriesConverter}, ConverterParameter=Datum}" />
</StackPanel>
<StackPanel Orientation="Horizontal">
<TextBlock Text="Hodnota: " FontWeight="Bold" />
<TextBlock Text="{Binding Path=., Converter={StaticResource seriesConverter}, ConverterParameter=Hodnota, StringFormat=F2}" />
</StackPanel>
</StackPanel>
</DataTemplate>

in code a write:

StackedBarSeries series2 = new StackedBarSeries();
//udalost kde pregeneruju titulek ktery se generuje blbe
series2.SeriesCreated += series2_SeriesCreated;
series2.Legend = this.xmLegend;
series2.XAxis = xAxis;
series2.YAxis = yAxis;
series2.AutoGenerateSeries = true;

//tooltip
var toolTipTemplate = this.DataChart.Resources["ToolTipTemplate"] as DataTemplate;
if (toolTipTemplate != null)
{
var toolTip = new ContentControl();
toolTip.ContentTemplate = toolTipTemplate;
Binding b2 = new Binding(".");
toolTip.SetBinding(ContentControl.ContentProperty, b2);
series2.ToolTip = toolTip;
}
series2.ItemsSource = gb;

this.DataChart.Series.Add(series2);

And code for convertor is:

public class SeriesConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
Infragistics.Controls.Charts.DataContext dc = value as Infragistics.Controls.Charts.DataContext;
if (dc != null)
{
Infragistics.Controls.Charts.AnchoredCategorySeries cs = dc.Series as Infragistics.Controls.Charts.AnchoredCategorySeries;
string klic = cs.ValueMemberPath.Replace("_Hodnota", string.Empty);
klic = klic + "_" + parameter.ToString();
Binding b = new Binding();
b.Path = new PropertyPath(klic);
b.Source = dc.Item;
FrameworkElement fe = new FrameworkElement();
fe.SetBinding(FrameworkElement.TagProperty, b);
fe.DataContext = dc.Item;
return fe.Tag;
}
else
{
return null;
}
}

public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
return null;
}
}
