I have editable combobox in WPF. which is having list of order number.
I need to implement below scenario in my code.
The user can fill the starting of order number, and, the system propose the close order number available in the dropdown list.

Can anyone suggest how to do that?

In My Viewmodel i have written:

        public void _fillREOrderNumbers()   

        {

            List<FinishedReprintingOrderNumber> orders = _finishedProductReprintService.GetFinishedProductReprintbyOrder().ToList();

            foreach (var item in orders)

            {

                ReOrders.Add(item);

            }

        }

This is loading the order number in drop down.

View or XAML:

<ComboBox x:Name="cbOFab" HorizontalAlignment="Left" Margin="373,81,0,0" 

 VerticalAlignment="Top" Width="262" IsEditable="True"  

 ItemsSource="{Binding ReOrders, Mode=TwoWay}"  DisplayMemberPath="codOrder" SelectedItem="{Binding 

 ReSelectedOrder}" Background="{DynamicResource dgridRowColor}" />

Till Now,
I am able to populate the order number in my combo box but I am not aware how to search inside it.

I have implemented filtering of items in ComboBox this way.

Here is XAML:

<ComboBox

MinWidth="200"

ItemsSource="{Binding Path=Shops.View, RelativeSource={RelativeSource TemplatedParent}}" 

DisplayMemberPath="NameExtended"

SelectedItem="{Binding Path=SelectedShop, Mode=TwoWay, RelativeSource={RelativeSource TemplatedParent}}"

IsTextSearchEnabled="False"

IsEditable="True"

IsDropDownOpen="{Binding Path=ComboOpen, Mode=TwoWay, RelativeSource={RelativeSource TemplatedParent}}"

StaysOpenOnEdit="True"

Text="{Binding Path=SearchText, Mode=TwoWay, RelativeSource={RelativeSource TemplatedParent}}"

>

<i:Interaction.Triggers>

    <i:EventTrigger EventName="KeyUp">

        <i:InvokeCommandAction 

            Command="{Binding Path=FilterCommand, RelativeSource={RelativeSource TemplatedParent}}" 

        />

    </i:EventTrigger>

</i:Interaction.Triggers>

You need all lines from IsTextSearchEnabled and below.

When you press any key in combo box, it opens in up and filters items in it, using property SearchText bound to ComboBox.Text.

Here is the view model code:

public string SearchText { get; set; }

private List<Shop> _shops;



protected void FilterShops()

    {

        ComboOpen = true;

        if (!string.IsNullOrEmpty(SearchText))

        {

            Shops.UpdateSource(_shops.Where(s => s.NameExtended.ToLower().Contains(SearchText.ToLower())));

        }

        else

        {

            Shops.UpdateSource(_shops);

        }

        OnPropertyChanged("Shops");

    }
