Hi, I have a scenario where dropdown items are not cleared in XamMultiColumnComboEditor when there is random text in the combo box.
Steps to reproduce :
How can I fix this? I want the situation to be like, if the search text dont match any of the items in the itemsSource, then on opening the dropdown, the Items count should be 0.
The situation is very well reproducible in the the below link.

Thanks and Regards,

Thanks Michael. Would do that.
Hi Kaushik,
The XamMultiColumnComboEditor does not expose a way to trigger the internal filtering.
A method to perform the filtering in the combo has been determined to be a product idea. You can suggest new product ideas for future versions by emailing ideas@infragistics.com.
Submitting your idea will send it directly to our product management team so that it can be imported into our new ideas community once live: http://ideas.infragistics.com.
Remember when submitting your idea to explain the context in which a feature would be used and why it is needed as well as anything that would prevent you from accomplishing this today. You can even add screenshots to build a stronger case. You can also link back to this thread for additional details.
Thank you in advance to submitting your product idea.

Yes, we can surely do this. But, instead of filtering manually, is there anyway we can raise the event that gets fired when we do step 1.
Hello Kaushik,
Please see the modified sample I have attached that demonstrates how you can achieve this.
1565.XamMultiColumnComboEditor_modified.zip
Here, I subscribed to the XamMultiComboEditor's internal TextBox's TextChanged event. This allows us to manually filter the ItemSource with any custom logic.
With the current implementation I am using, when selecting multiple items, the text will clear out and not deselect any items. You should tweak the algorithm for filtering the data to meet all your specific needs.
If you need further assistance with this, please let me know.
Thank you for posting in our forums!
I am able to reproduce this and will need a little more time to investigate how the dropdown list should show the expected results.
I will have more information on my findings for you tomorrow.
