WPF Toolkit Data Grid crashing on Binding to 16K row DataTable
I am working on a recreation of a search control using the MVVM pattern. Our current implementation does a lot of code-behind work to create this control.
I have a WPF Toolkit Datagrid in SearchControl.xaml
<wtk:DataGrid Name="ResultsGrid"
Grid.Row="4"
Grid.ColumnSpan="4"
Height="Auto"
AutoGenerateColumns="True"
ItemsSource="{Binding Path=.}"
DataContext="{Binding Path=Results}"
CanUserAddRows="False"
CanUserDeleteRows="False"
IsReadOnly="True"
AutoGeneratedColumns="ResultsGrid_AutoGeneratedColumns"
VerticalScrollBarVisibility="Auto"/>
The control is bound to a SearchControlViewModel, which has a Results property
public DataTable Results
{
get { return _results; }
set
{
_results = value;
OnPropertyChanged("Results");
OnPropertyChanged("ShowResults");
}
}
This works fine for smaller data sets, but crashes when given a data table with 16K+ rows. This is essentially a copy of paste reproduction of what is currently imp开发者_如何学JAVAlemented, with the main difference being applying the DataGrid's data context via Binding rather than setting it in the code-behind.
Thanks for any help.
My data grid was not being properly contained by it's parent causing it to not have a vertical size limit. All the rows were being displayed and no virtualization was occurring.
