Datapager in silverlight 4 -Nested datagrid visibility issue
- by Archie
I have a datagrid in silverlight with child datagrid nested in it. Also I have a DataPager on the outer datagrid.
The code looks like this:
<data:DataGrid x:Name="dgData" Width="600" ItemsSource="{Binding}" AutoGenerateColumns="False" IsReadOnly="True"
HorizontalScrollBarVisibility="Hidden" CanUserSortColumns="False" RowDetailsVisibilityChanged="dgData_RowDetailsVisibilityChanged" Margin="20,0" Grid.RowSpan="2">
<data:DataGrid.Columns>
<data:DataGridTextColumn Header="Item" Width="*" Binding="{Binding ItemName,Mode=TwoWay}"/>
<data:DataGridTextColumn Header="Company" Width="*" Binding="{Binding Company,Mode=TwoWay}"/>
</data:DataGrid.Columns>
<data:DataGrid.RowDetailsTemplate>
<DataTemplate>
<data:DataGrid x:Name="dgRowDetail" Width="400" HorizontalScrollBarVisibility="Hidden" AutoGenerateColumns="False" Visibility="Collapsed">
<data:DataGrid.Columns>
<data:DataGridTextColumn Header="Date" Width="*" Binding="{Binding Date,Mode=TwoWay}"/>
<data:DataGridTextColumn Header="Price" Width="*" Binding="{Binding Price,Mode=TwoWay}"/>
</data:DataGrid.Columns>
</data:DataGrid>
</DataTemplate>
</data:DataGrid.RowDetailsTemplate>
</data:DataGrid>
<data:DataPager x:Name="dpData" HorizontalAlignment="Center" DisplayMode="FirstLastPreviousNextNumeric" Source="{Binding}"/>
I have one PagedCollectionView pgv which is bound to outer datagrid as:
DataContext = pgv;
When the row is clicked I set the child datagrid's ItemsSource property to another PagedCollectionView.
My problem is it works fine except for the first row for the first time. When I click on it, it doesn't fire the dgData_RowDetailsVisibilityChanged event.
Also, when I click on second row, firstly first row fires the event and then the second row fires it and shows the nested grid.
Please help.
