Export Chart to PDF without rendering

[Gerrit]

Hello 

I have a a TabControleExt with a few TabItems and in each of these items is a SfChart. I want to export these Charts as Streams without necessarily viewing them. When I do this I get this error when trying to Save the chart to a Stream. 

The parameter value must be greater than zero. (Parameter 'pixelWidth')

I have set the Measure and Arrange manually like so:

chart.Background = new SolidColorBrush(Colors.White);

chart.Measure(new Size(double.PositiveInfinity, double.PositiveInfinity));

chart.Arrange(new Rect(new Size(700, 500)));

But even this did not fix the problem.. When I set the height and width manually it works but I don't want to set it to a fixed value. How can I fix this.

Hi Gerrit, 

 

Sorry for the delay.  

 

We analyzed your query, and we would like to let you know that “The parameter value must be greater than zero. (Parameter 'pixelWidth')” exception may occur when trying to save the chart even it is not in UI. If it so, we need to call Measure() and arrange() methods of chart manually before saving it. Please refer below sample,
