ComboBoxItems displaying object instead of property when selected

Question

I have encountered the following problem:

ISSUE: ComboBoxItems displaying perfectly but displaying whole object when items are selected.

1. Clicking on comboBox: ComboBoxItems displaying perfectly

2. One ComboBoxitem is selected: Whole Entity Framework object is displayed instead of just item name.

Here is an example of what is displayed when a ComboBoxItem is selected: System.Data.Entity.DynamicProxies.tblContainer_C0BE4F13C798ED380A1E249BFB338D265E97D4F4C7A880C5D813102738561025

Desired result: Bout verre bouchon emery

This is a minified version of my code:

<ComboBox IsEditable = "True" ItemsSource="{Binding ProductsContainer}" SelectedValuePath="ContainerID">
                            <ComboBox.ItemTemplate>
                                <DataTemplate>
                                    <TextBlock 
                                        FontSize="15"
                                        Width="100"
                                        HorizontalAlignment="Center"
                                        Text="{Binding ContainerName}" 
                                        TextWrapping="Wrap" />
                                </DataTemplate>
                            </ComboBox.ItemTemplate>
</ComboBox>

Here is the list to which the ComboBox binds:

public virtual List<tblContainer> ProductsContainer { get { return db.tblContainer.ToList(); } }

ProductsContainer has the attributes: ContainerID and ContainerName

add the code of the class tblContainer or at least the minimal code needed for your example to work. — Blechdose
You probably don't want to set IsEditable to true. The ItemTemplate is not applied then. See e.g. here: stackoverflow.com/q/27636357/1136211 — Clemens

Seems to work when IsTextSearchEnabled="True"and TextSearch.TextPath="ContainerName" is used.

<ComboBox IsEditable="True" ItemsSource="{Binding ProductsContainer}" SelectedValuePath="ContainerID" 
          IsTextSearchEnabled="True" TextSearch.TextPath="ContainerName">
        <ComboBox.ItemTemplate>
            <DataTemplate>
                <TextBlock 
                    FontSize="15"
                    Width="100"
                    HorizontalAlignment="Center"
                    Text="{Binding ContainerName}" 
                    TextWrapping="Wrap" />
            </DataTemplate>
        </ComboBox.ItemTemplate>
    </ComboBox>
