c# - How to set ItemsSource value of ColumnSeries? -

-

i not able set itemssource value of columnseries. following examples (this , this) seem out dated.

here xaml:

<charting:chart x:name="columnchart"                 horizontalalignment="center"                 verticalalignment="center"                 width="auto"                 height="auto">     <charting:columnseries title="georgi kyuchukov"                            margin="0"                            name="columnchartseries"                            independentvaluepath="name"                            dependentvaluepath="pts"                            isselectionenabled="true" /> </charting:chart>

and here c# code:

public class chartdata {     public string name { get; set; }     public int pts { get; set; } }  protected override void onnavigatedto(navigationeventargs e) {     list<chartdata> personaldata = (list<chartdata>)e.parameter;      foreach (chartdata x in personaldata){         debug.writeline(x.name + " " + x.pts);     }      (columnchart.series[0] columnseries).itemssource = personaldata;     //columnchartseries.itemssource = personaldata; }

i getting following error:

error 1 type or namespace name 'columnseries' not found (are missing using directive or assembly reference?)

i have try:

columnchartseries.itemssource = personaldata;

but get:

an exception of type 'system.nullreferenceexception' occurred in gotqn.exe not handled in user code.

also, getting following error often:

error 1 value of type 'columnseries' cannot added collection or dictionary of type 'collection`1'.

but able run application, guess not critical.

could tell doing wrong?

also, grateful being given up-to-dated documentation link/article.

perhaps you're missing in code behind...

using winrtxamltoolkit.controls.datavisualization.charting;

try moving cursor columnseries , press alt+shift+f10 add missing namespace. or use alt+enter if have resharper (which recommend).
