UI Freeze when Navigation a page to another in xamarin forms - xamarin

Question

In my application My MainPage Showing Menus and after clicking menu the next page loading very slow and freeze the UI.
This happen when the content page contain a listView with Items.
My Data Page Content a listView with 50 items(Infinite Scrolling First 50 items)
XAML:
<ListView
ItemsSource="{Binding ItemsData}"
SelectedItem="{Binding SelectedItemsData}"
HasUnevenRows="True"
BackgroundColor="White" x:Name="ItemsDataList">
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<Grid
Margin="2,0,2,0"
Padding="8"
IsEnabled="{Binding IsEnableItemsData}">
<Grid.RowDefinitions>
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="30*"/>
<ColumnDefinition Width="30*"/>
<ColumnDefinition Width="30*"/>
<ColumnDefinition Width="20*"/>
<ColumnDefinition Width="20*"/>
</Grid.ColumnDefinitions>
<Label Text="{Binding SKU}" Grid.Row="0" Grid.Column="0" HorizontalTextAlignment="Center" VerticalOptions="Center" TextColor="{Binding SKUColor}" FontSize="Small"/>
<Label Text="{Binding OrderNumber}" Grid.Row="0" Grid.Column="1" HorizontalTextAlignment="Center" VerticalOptions="Center" TextColor="Black" FontSize="Small"/>
<Label Text="{Binding CategoryName}" Grid.Row="0" Grid.Column="2" HorizontalTextAlignment="Center" VerticalOptions="Center" TextColor="Black" FontSize="Small"/>
<Label Text="{Binding OrderQuantity}" Grid.Row="0" Grid.Column="3" HorizontalTextAlignment="Center" VerticalOptions="Center" TextColor="Black" FontSize="Small"/>
<Label Text="{Binding Bin}" Grid.Row="0" Grid.Column="4" HorizontalTextAlignment="Center" VerticalOptions="Center" TextColor="Black" FontSize="Small"/>
</Grid>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
<ListView.Behaviors>
<eventToCommand:EventToCommandBehavior
EventName="ItemSelected"
Command="{Binding ItemsDataSelectedItemChange}"/>
<eventToCommand:EventToCommandBehavior
EventName="ItemAppearing"
Command="{Binding ItemsDataItemAppearing}"/>
</ListView.Behaviors>
</ListView>
ViewModel:
public ObservableCollection<ItemsData> Data
{
get { return _data; }
set
{
_data = value;
RaisePropertyChanged();
}
}
Getting the data from Local Database
Data = GetData(GlobalVariable.BranchId, DataLimit, Offset, SearchText, filterData, "Others", sortData);
How to get rid of this issues?
