[George Sterg]

Using a StackColumn a want to show a tooltip with the above elements: The legend, the label and the X and YData. . Everytging is working except the label. My data template is the above:


 DataTemplate template = new DataTemplate();
            FrameworkElementFactory border = new FrameworkElementFactory(typeof(Border));
            border.SetValue(Border.BackgroundProperty, Brushes.WhiteSmoke);
            border.SetValue(Border.CornerRadiusProperty, new CornerRadius(5, 5, 5, 5));
            border.SetValue(Border.PaddingProperty, new Thickness(3.0));
            border.SetValue(Border.BorderBrushProperty, Brushes.LightGray);
            border.SetValue(Border.BorderThicknessProperty, new Thickness(2.0));

            FrameworkElementFactory stackpanelVertical = new FrameworkElementFactory(typeof(StackPanel));
            stackpanelVertical.SetValue(StackPanel.OrientationProperty, Orientation.Vertical);

            FrameworkElementFactory stackpanelLegend = new FrameworkElementFactory(typeof(StackPanel));
            stackpanelLegend.SetValue(StackPanel.OrientationProperty, Orientation.Horizontal);

            FrameworkElementFactory chartLegend = new FrameworkElementFactory(typeof(Syncfusion.UI.Xaml.Charts.ChartLegend));
            chartLegend.SetValue(Syncfusion.UI.Xaml.Charts.ChartLegend.HorizontalAlignmentProperty, HorizontalAlignment.Stretch);
            chartLegend.SetValue(Syncfusion.UI.Xaml.Charts.ChartLegend.VerticalAlignmentProperty, VerticalAlignment.Center);
            chartLegend.SetValue(Syncfusion.UI.Xaml.Charts.ChartLegend.HorizontalContentAlignmentProperty, HorizontalAlignment.Stretch);
            chartLegend.SetValue(Syncfusion.UI.Xaml.Charts.ChartLegend.VerticalContentAlignmentProperty, VerticalAlignment.Center);
            Binding chartLegendBinding = new Binding();
            chartLegendBinding.Path = new PropertyPath("Interior");
            chartLegend.SetValue(Syncfusion.UI.Xaml.Charts.ChartLegend.BackgroundProperty, chartLegendBinding);

            FrameworkElementFactory txtblockLabel = new FrameworkElementFactory(typeof(TextBlock));
            txtblockLabel.SetValue(TextBlock.FontSizeProperty, 12.0);
            txtblockLabel.SetValue(TextBlock.VerticalAlignmentProperty, VerticalAlignment.Center);
            txtblockLabel.SetValue(TextBlock.HorizontalAlignmentProperty, HorizontalAlignment.Stretch);
            txtblockLabel.SetValue(TextBlock.ForegroundProperty, Brushes.Black);
            Binding label = new Binding();
            label.Path = new PropertyPath("Label");
            label.Converter = new LegendValueConverter();
            txtblockLabel.SetValue(TextBlock.TextProperty, label);


            FrameworkElementFactory stackpanelValues = new FrameworkElementFactory(typeof(StackPanel));
            stackpanelValues.SetValue(StackPanel.OrientationProperty, Orientation.Horizontal);

            FrameworkElementFactory txtblockX = new FrameworkElementFactory(typeof(TextBlock));
            txtblockX.SetValue(TextBlock.FontSizeProperty, 12.0);
            txtblockX.SetValue(TextBlock.VerticalAlignmentProperty, VerticalAlignment.Center);
            txtblockX.SetValue(TextBlock.HorizontalAlignmentProperty, HorizontalAlignment.Stretch);
            txtblockX.SetValue(TextBlock.ForegroundProperty, Brushes.Black);
            Binding XDataBinding = new Binding();
            XDataBinding.Path = new PropertyPath("Item");
            XDataBinding.Converter = new ValueConverter();
            txtblockX.SetValue(TextBlock.TextProperty, XDataBinding);

            FrameworkElementFactory txtblockSeperator = new FrameworkElementFactory(typeof(TextBlock));
            txtblockSeperator.SetValue(TextBlock.FontSizeProperty, 12.0);
            txtblockSeperator.SetValue(TextBlock.VerticalAlignmentProperty, VerticalAlignment.Center);
            txtblockSeperator.SetValue(TextBlock.HorizontalAlignmentProperty, HorizontalAlignment.Stretch);
            txtblockSeperator.SetValue(TextBlock.ForegroundProperty, Brushes.Black);
            txtblockSeperator.SetValue(TextBlock.TextProperty, ":");

            FrameworkElementFactory txtblockY = new FrameworkElementFactory(typeof(TextBlock));
            txtblockY.SetValue(TextBlock.FontSizeProperty, 12.0);
            txtblockY.SetValue(TextBlock.VerticalAlignmentProperty, VerticalAlignment.Center);
            txtblockY.SetValue(TextBlock.HorizontalAlignmentProperty, HorizontalAlignment.Stretch);
            txtblockY.SetValue(TextBlock.ForegroundProperty, Brushes.Black);
            Binding YDataBinding = new Binding();
            YDataBinding.Path = new PropertyPath("YData");
            YDataBinding.StringFormat = NumberFormat;
            txtblockY.SetValue(TextBlock.TextProperty, YDataBinding);
        

            stackpanelLegend.AppendChild(chartLegend);
            stackpanelLegend.AppendChild(txtblockLabel);
           
            stackpanelValues.AppendChild(txtblockX);
            stackpanelValues.AppendChild(txtblockSeperator);
            stackpanelValues.AppendChild(txtblockY);

            stackpanelVertical.AppendChild(stackpanelLegend);
            stackpanelVertical.AppendChild(stackpanelValues);
            border.AppendChild(stackpanelVertical);
            template.VisualTree = border;

            return template;           

Any help?

Thanks

Hi George,

Thank you for contacting our Syncfusion support.

I have analyzed your requirement and you can get the “Label” of the series in the converter as specified in the below code snippet.

publicclassLegendValueConverter:IValueConverter
{
publicobjectConvert(objectvalue,TypetargetType,objectparameter,System.Globalization.CultureInfoculture)
{
return(valueasChartSegment).Series.Label;
}

}


We have prepared a sample based on your requirements. Please find the sample in the following attachment.
