[Solved] Paging & Filtering using RadGridView, DataPager and QueryableCollectionView

[Justin Brown]

Hi,

I'm using the 2009 Q3 beta 2 as I'd read there were some fixes with the QueryableCollectionView. I've created a test page with a RadGridView as below:

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="40"/>
        <RowDefinition Height="Auto"/>
    </Grid.RowDefinitions>

    <telerikGridView:RadGridView Grid.Row="1" d:LayoutOverrides="Width" MaxWidth="600"
        DataContext="{StaticResource _designTimeViewModel}"
        ItemsSource="{Binding Path=Results}" />

    <data:DataPager DataContext="{StaticResource _designTimeViewModel}"
        Source="{Binding Path=Results}" VerticalAlignment="Top"/>

</Grid>

The RadGridView and DataPager are both bound to the Results property, which is of type QueryableCollectionView.

I was pleased to see that the DataPager works better in Q3 than in Q2, however if I apply a filter, it breaks, with all pages except the first displaying no rows in the grid.

Does anyone have any suggestions?

Thanks
Justin

Hello Justin,

I've just tested the grid performance with our latest binaries using the same scenario however everything worked fine. You can check the attached demo.

Hi Vlad,

Thank you very much for looking into this. Do you have access to a newer build than what is available on the beta downloads page? I found that by plugging your DLLs into my project it fixed my issues, and by plugging my DLLs into yours it reproduced it. The versions appear the same however.

Will you guys be posting a newer beta build up soon?

Thanks,
Justin
