Filter doesnt show all objects

[Tobias]

Hello everyone,

I have a large amount of objects which I want to filter. My problem is that if i use the filter it seems that many objects get lost. Maybe you should have a look at the picture to understand want I mean. Does anyone know how I could fix this?

Thanks for your help!

Hello Tobias,

By design, the filtering control shows the first 1000 distinct values. You can control this behavior using DistinctValuesLoading event of RadGridView. Please follow Display All Distinct Values help article for more information.

Thank you for your answer.
I used the code snippet and connected the DistinctValuesLoading event of RadGridView to the method. But the method doesn't get triggered. I have no idea why.

<telerik:RadGridView x:Name="myRadGridView"
                         Margin="-1"
                         SelectionMode="Extended"
                         IsReadOnly="True"
                         IsFilteringAllowed="True"
                         ShowGroupPanel="False"
                         ItemsSource="{Binding GridSource}" Unloaded="Gridview_unload" Loaded="Gridview_load" DistinctValuesLoading="OnRadGridViewDistinctValuesLoading" />

private void OnRadGridViewDistinctValuesLoading(object sender, Telerik.Windows.Controls.GridView.GridViewDistinctValuesLoadingEventArgs e)
{
    e.ItemsSource = ((Telerik.Windows.Controls.RadGridView)sender).GetDistinctValues(e.Column, true, null);
}

Hi,

It should trigger when you actually open the filtering popup. If that is not the case, please send us a small dummy repro-project which we can debug on our side. We tested this and the event is raised.
