ComboBoxAdv Property Binding

Hello
I'm using Syncfusion WPF ComboBoxAdv setting IsEditable to True (using like a textbox with suggestions).
My problem is binding its Text Property does not seem to work.
I also tried with Syncfusion SfTextBoxExt and plain WPF ComboBox. Both worked
Is this not supported? Are there any alternatives?
Thank you.

XAML:
    <syncfusion:ComboBoxAdv IsEditable="True" Text="{Binding PropertyName}" Width="150" /> <!-- not work -->
    <syncfusion:SfTextBoxExt Text="{Binding PropertyName}" Width="150"/>                   <!-- work -->
    <ComboBox IsEditable="True" Text="{Binding PropertyName}" Width="150" />               <!-- work -->

Hi Jun 
 
Thank you for contacting Syncfusion support. 
 
We have checked the reported behavior regarding "Binding with ComboBoxAdv's Text property does not work properly". However we would able to observe the bounding the Text property is not worked for ComboBoxAdv and also for other two component such as SfTextBoxExt and Ms ComboBox . Please find the sample. 
 
 
So please check our sample and confirm us our replication is same. Upon your confirmation, we could able to proceed on this further.

Hi Jun 
 
Thank you for your update. 
 
We have checked the reported behavior that values are not bounded correctly at runtime and on property changed in ComboBoxAdv. In order to update the values on Propertychanged , you need to set the Mode as TwoWay. Please find the code for the same below: 
 
Code:[XAML] 
 
   
<syncfusion:ComboBoxAdv IsEditable="True"  Height="23" Text="{Binding Name,Mode=TwoWay}"  Margin="0,0,0,5" Width="150" /> 
 
 
 
 
Please try this solution and let us know if it is helpful.

Thank you for you reply and the sample.
I tried your sample and I confirmed it worked. Thank you.
But I found one more problem that hitting Enter key on the ComboBoxAdv stop refreshing the change of the Text property.
That behavior was not seen on the SfTextBoxExt and Ms ComboBox.
Is this expected behavior? Is there a way to fix it?

Edit:
Sorry for my bad English.
I meant when I hit the  Enter Key on the ComboBoxAdv it stopped refreshing the change of the Text property.

Hello,

Thank you for fixing the problem and creating patch.
I applied that patch and checked behavior.
As a result, I confirmed it kept reflecting the value of its Text property correctly even after I pressed enter.
Thank you very much.

But I found another problem.
After I selected an item from dropdown menu, it stopped updating the value of its text property.
This behavior was not seen on MS ComboBox.

I attached project files. Would you check this?

Thank you.

Hi,

Thank you for your reply and patch.

I applied the patch and checked its behavior.
The problem about selecting dropdown menu had been fixed. Thank you.

But it seems to have probrems yet.

One problem is that the text set to its text property in xaml was not displayed at run time. The ComboBoxAdv showed empty string on its textbox.(with IsEditable = true)
Another problem is that when I edited the text on it (editable ComboBoxAdv) but its text property value didn't reflect the text edited.

I attached my project and screenshot. Would you check this?
I'm sorry if it does not make sense. Please don't hesitate to ask.

Thank you.
