Possible bug with 0.8.3091.*

[cosullivan]

Hi,

I am getting a null reference exception when View3D is enabled and the ItemsSource is either null or an empty list.

Is there a better method of reporting bugs (ie, any public bug tracker?) 

 

<

cfx:Chart x:Name="chart1" Gallery="Pie" BorderThickness="0">

<cfx:SeriesAttributes BindingPath="Actual" />

<cfx:Chart.View3D>

<cfx:View3D IsEnabled="true" />

</cfx:Chart.View3D>

</cfx:Chart>

We have fixed this issue, note that in the fixed build you will get a "No Data Available" message which is the same behavior you would get in a 2D chart. This message is customizable (both as a string or replacing it with xaml content)

You can request a hotfix by sending a message to wpf at softwarefx dot com

This forum is the preferred way to report bugs as well as to request help.

Thanks.

How do I customize the "No Data Available" message? Is it just the message text that can be customizable or the control template?

 

[JuanC]

You can provide new text or you can provide a new data template, e.g. to change the text in code you would write the following

  chart1.MessageTable["NoData"] = "Downloading data, please wait...";

To change the data template in XAML you can do this

<cfx:Chart.MessageTable>

  <cfx:ContentTableItem Key="NoData">

  <DataTemplate>

  <StackPanel Orientation="Horizontal">

  <Rectangle Width="16" Height="16" Fill="Red"/>

  <TextBlock Text="Empty Chart"/>

  </StackPanel>

</DataTemplate>

  </cfx:ContentTableItem>

</cfx:Chart.MessageTable>
