Grouping Listview Items By Ignoring Case Sensitivity

Updated on Sep 24, 2025

Grouping the items by ignoring case sensitive by using the KeySelector property in the GroupDescriptor. While returning the KeySelector, convert the required property name in the data model to group either as Upper or Lower case. The items will be grouped based on the KeySelector with returned case sensitive.

Sample

<listView:SfListView x:Name="listView" ItemSize="100"
                      AutoFitMode="Height"
                      ItemsSource="{Binding ContactsInfo}" 
                      ItemSpacing="10">

  <listView:SfListView.GroupHeaderTemplate>
    <DataTemplate>
      <ViewCell>
        <ViewCell.View>
          <code>
          . . .
          . . .
          <code>
        </ViewCell.View>
      </ViewCell>
    </DataTemplate>
  </listView:SfListView.GroupHeaderTemplate>

  <listView:SfListView.ItemTemplate>
    <DataTemplate>
      <ViewCell>
        <ViewCell.View>
          <code>
          . . .
          . . .
          <code>
        </ViewCell.View>
      </ViewCell>
    </DataTemplate>
  </listView:SfListView.ItemTemplate>
</listView:SfListView>

listView.DataSource.GroupDescriptors.Add(new GroupDescriptor() 
{ 
  PropertyName = "ContactName", 
  KeySelector = (object obj) => 
  { 
    return (obj as Contacts).ContactName.ToUpper()[0];
  } 
});
