Dear Forum,

I am a relatively new developer of Infragistics.

Currently I am trying to save the order and the Width of the Fieldlayout - Fields in a XamTreeGrid.

When I save the PersistenceManager.Save it creates a XML File 

Only Loading causes a Crash.

Here the Code

[Code]

<Custom:XamTreeGrid x:Name="myTreeGrid" BindToSampleData="True" IsSynchronizedWithCurrentItem="False" Margin="0,0,6,3" Theme="IGTheme">
<Custom:XamTreeGrid.FieldLayoutSettings>
<Custom:FieldLayoutSettings AutoArrangeCells="Never" AutoGenerateFields="False"/>
</Custom:XamTreeGrid.FieldLayoutSettings>
<Custom:XamTreeGrid.FieldSettings>
<Custom:FieldSettings CellHeight="80" FilterClearButtonVisibility="Visible" FilterEvaluationTrigger="Default"/>
</Custom:XamTreeGrid.FieldSettings>
<Custom:XamTreeGrid.FieldLayouts>
<Custom:FieldLayout>
<Custom:Field Name="email" Row="0" Column="0" Width="60"/>
<Custom:Field Name="name" Row="0" Column="1" Width="70"/>
<Custom:Field Name="salary" Row="0" Column="2" Width="80"/>
<Custom:Field Name="department" Row="0" Column="3" Width="90"/>


</Custom:FieldLayout>
</Custom:XamTreeGrid.FieldLayouts>
</Custom:XamTreeGrid>

[/Code]
