I need to display two columns of dataset; first column is the Checkbox items and second column would be just a list<string>
I am able to build first column (grid.column=0) using Listbox with Checkbox in XAML as:
<Grid Grid.Row="0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<ListBox x:Name="Listitems" Grid.Column="0" SelectionMode="Multiple" ItemsSource="{Binding MonthlyResults}" >
<ListBox.ItemTemplate>
<DataTemplate>
<CheckBox Content="{Binding logdate}" IsChecked="{Binding Checked ,Mode=TwoWay}"
Click="CheckBox_Click"/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
User interface is displayed correctly as:
For the second column, I thought of using a ListView(grid.colum=1) and updated the above XAML as:
<Grid Grid.Row="0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<ListBox x:Name="Listitems" Grid.Column="0" SelectionMode="Multiple" ItemsSource="{Binding MonthlyResults}" >
<ListBox.ItemTemplate>
<DataTemplate>
<CheckBox Content="{Binding logdate}" IsChecked="{Binding Checked ,Mode=TwoWay}"
Click="CheckBox_Click"/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
<ListView Grid.Column="1" Name="CatNames" FontSize="13" SelectionMode="Extended"
ItemsSource="{Binding Path=OFMCategoriesNames}" IsSynchronizedWithCurrentItem="False" >
</ListView>
</Grid>
But the user interface is messed up. Both columns have their own scrollbars.

How to display the columns in the same listbox ?
*************Update based on the answer provided*************** I updated the XAML as:
<Grid Grid.Row="0">
<ListBox x:Name="Listitems" SelectionMode="Multiple" ItemsSource="{Binding MonthlyResults}" >
<ListBox.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" SharedSizeGroup="A1"/>
<ColumnDefinition Width="*" SharedSizeGroup="A2"/>
</Grid.ColumnDefinitions>
<CheckBox Grid.Column="0" Content="{Binding logdate}" IsChecked="{Binding Checked ,Mode=TwoWay}" Click="CheckBox_Click"/>
<ListView Grid.Column="1" Name="CatNames" FontSize="13" SelectionMode="Extended"
ItemsSource="{Binding MeasureMethod}" IsSynchronizedWithCurrentItem="False" >
</ListView>
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
Even after adding "sharedsizegroup", the columns are not aligned properly..
