I will create a support case on your behalf so that we can continue the discussion there.

Hi Alex. I know we have to similiar threads working the same problem. It seems the grid in the combo it proving to be to complicated.

What I'm trying to mimic is the following example I have using a ComboBox. I can't seem to mirror the same functionality with a XamComboBox.

Basically I have a Users List with 3 columns. Name, Phone and SocialSecurity number. I bind it as the Item Source (athough I would plan to use and ItemsProvider if I can get this to work for the XamComboEditor. Using the Items template selector I either want to show it one way (when the combo is opened with the 3 columns. or another when the user selects a comboItem (just one column).  How do I do this with the XamCombo? Essentially this is exaactly what I want but I want to use your control.

Here is my xaml.

<ComboBox Margin="138,39,20,0" Name="comboBox1" ItemsSource="{Binding Users}" SelectedValuePath="Name" SelectedValue="{Binding User}" Height="23" VerticalAlignment

="Top">

<ComboBox.ItemTemplateSelector

>

<WPFSandbox:TemplateSelector

/>

</ComboBox.ItemTemplateSelector

>

<ComboBox.Resources

>

<DataTemplate x:Key

="DropDownTemplate">

<StackPanel Orientation

="Horizontal">

<TextBlock Text="{Binding Name}" Width

="100" />

<TextBlock Text="{Binding Phone}" Width

="100" />

<TextBlock Text="{Binding SocialSecurity}" Width

="100" />

</StackPanel

>

</DataTemplate

>

<DataTemplate x:Key

="SelectionTemplate">

<StackPanel Orientation

="Horizontal">

<TextBlock Text="{Binding Name}" Width

="100" />

</StackPanel

>

</DataTemplate

>

</ComboBox.Resources

Here is the Template Selector:

DataTemplateSelector

container)

{

)container;

)

);

// Templated parent is ComboBoxItem

);

>

</ComboBox

>

Thanks again for all the help.. Sorry for the multiple posts..

This is because the XamComboEditor has not ended its edit mode and the value is not updated until then. It ends edit mode when you click away (lose focus), so you need to force it to end edit mode when you select an item:

x.EndEditMode(true,true);

You have not provided any code-behind (the part where you select an item) so I really cannot give you the exact code, but you should call the EndEditMode(...) of the XamComboEditor when the item is selected.

Hi Alex.  If I set the DisplayMember prop it does show the correct item when I click away from the ComboBox. The problem is when I select the item it then shows that entire item in the combobox till I click away. How do we make it so it just shows the one item as if I did click away?

I know you did something like this in the other example but since it's mixed up with all the gris stuff I couldn't figure out what to do. Can you look at the sample code I attached in my previous post give an example from that?

Thanks for all the help..
