I've look at the documentation and I didn't see anything describing this, maybe I just missed it. If thats the case I would love to be pointed in the right direction
thanks in advance,

Please try setting CanAutocompleteSelectItems property of the ComboBox to false and StaysOpenOnEdit and
OpenDropDownOnFocus to true, also bind SelectedItem property instead of Text - it will be updated when the item is selected with "Enter" or with the mouse:<
telerik:RadComboBox
Width
=
"200"
x:Name
=
"radComboBox"
IsEditable
=
"True"
ItemsSource
=
"{Binding Source={StaticResource DataSource}, Path=Items}"
DisplayMemberPath
=
"Name"
CanAutocompleteSelectItems
=
"false"
StaysOpenOnEdit
=
"True"
OpenDropDownOnFocus
=
"True"
SelectedItem
=
"{Binding Source={StaticResource DataSource}, Path=SelectedItem, Mode=TwoWay}"
/>
Hope this helps.

StaysOpenOnEdit is not marked as obsolete yet, but you're right that it's not needed. I'm sorry for my confusion.
I've attached our test project and a short video showing that the described approach works as expected at our side. Could you please check them and let us know what is different in your case?

Can you please confirm that you're using Q1 2011 SP1 version of the RadControls? Also can you send us a short video showing the problem? Thanks in advance

1. Start the project, click in the combobox and starttyping something that would be in the list. At this point everything should be working well.
2. To Submit a choice, hit enter. First time through this works nicely, the selected item doesn't get updated until the very end.
3. click back into the project and start typing. At this point you should be able to notice the SelectedItem getting updated every keystroke.
The SelectedValue of the RadComboBox is updated on every keystroke when the dropdown is closed - is this the situation that you're describing? Currently this is the default behavior of the ComboBox, but we'll consider changing it.

Has there been an update to this, or is there any other way of NOT updating the source with each keystroke when the autocomplete dropdown is not open?
I have a RadGridView with a column as below, and the bindings are working however the source is updated with each keystroke and I want it only updated when the user finishes editing.
<telerik:GridViewDataColumn Header="Axis" Width="*" DataMemberBinding="{Binding Axis, Mode=TwoWay}"
CellStyle="{StaticResource NormalCellStyle}" >
<telerik:GridViewColumn.CellEditTemplate>
<DataTemplate>
<telerik:RadComboBox x:Name="AxisCB" ItemsSource="{Binding Source={StaticResource AxisListViewSource}}" Text="{Binding Path=Axis, Mode=TwoWay}"
EmptyText="" IsEditable="True" >
</telerik:RadComboBox>
</DataTemplate>
</telerik:GridViewColumn.CellEditTemplate>
</telerik:GridViewDataColumn>
I am afraid that the behavior is not changed and the value is still updated on every keystroke when the dropdown is closed. We're sorry for the inconvenience.
All the best,
