How to Check/Unchech a serie in codebehind

[Rodolphe Billottet]

Hi,

I would like to programmatically  check or uncheck all the series with a shortcut for instance.  

My user want to quickly hide or show all series. 

I tried the code below with the visibility which works on the series but the check box in the legend is not updated.

checkAll = !checkAll;

 foreach (FastLineSeries cs in this.lineChart.Series)            

 {                      

    cs.Visibility = checkAll ? Visibility.Visible : Visibility.Hidden;  

}

 

I want the same behavior as  click on the check box of the legend.

Hi Rodolphe,

We have analyzed your requirements and we would like to inform you that the check box in the legend is updated if we set the IsSeriesVisible instead of Visibility property in chartseries. Please find the sample in the following location.

 

Code Snippet[C#]:

checkAll = !checkAll;

foreach (FastLineSeries cs in this.lineChart.Series)            

{                      

    cs.IsSeriesVisible = checkAll ? true : false ;  

}

 

Please let us know if you have any queries.
