How to improve the GridComboBoxColumn dropdown item's opening time in UWP DataGrid?
GridComboBoxColumn in SfDataGrid loads the ComboBox as its edit element. When you bind a large collection as ItemsSource, the opening of the ComboBox dropdown is slow. You can overcome this problem by changing the ItemsPanel of ComboBox by editing its style. In the following code example VirtualizingStackPanel is loaded as ComboBox’s ItemsPanelTemplate to improve dropdown opening performance.
XAML
<syncfusion:SfDataGrid x:Name="grid"
AutoGenerateColumns="False"
AllowEditing="True"
AllowFiltering="True"
AllowSorting="True"
ItemsSource="{Binding OrderInfoCollection}"
ColumnSizer="Auto">
<syncfusion:SfDataGrid.Resources>
<ResourceDictionary>
<Style TargetType="ComboBox">
<Setter Property="ItemsPanel">
<Setter.Value>
<ItemsPanelTemplate>
<VirtualizingStackPanel/>
</ItemsPanelTemplate>
</Setter.Value>
</Setter>
</Style>
</ResourceDictionary>
</syncfusion:SfDataGrid.Resources>
</syncfusion:SfDataGrid>
