Force user to only select from the available list

[Jean]

Hi,

By default the AutoCompleteBox behaves like a free-text control, whereby one can type any text.
If the input text has any match, these show in the dropdown, else the dropdown is blank.

How can i force the user to only select from the available list of items?


Thanks,
Olivier.

Hi,

I'm having the same problem.
When I type out the full value, my selected item is null. 

Pretty similar to an older issue: (http://www.telerik.com/community/forums/wpf/autocompletebox/when-user-types-out-full-item-name.aspx)
Is this fixed by now?

Thanks in advance,
Dieter

Hi guys,

Oliver, for this scenario you may need to use RadComboBox instead of the AutoCompleteBox. You would just need to its IsEditable and IsReadOnly properties to true - this way the user will be only able to type only from the items in ComboBox. Please give it a try and let us know if this works for you.

Dieter, in the current implementation when you have typed the full value and press Enter or lose the focus the matched item has been selected.

Hope this helps.

Hi Kalin, 

I am wanting to force the User to only select from the Available list too. 

You have given a solution of using the RadComboBox - but I am currently switching from the RadComboBox to the AutoCompleteBox due to other restrictions with the RadComboBox.

Please can you tell me if there is any way of getting this behaviour for the AutoCompleteBox please.

Thanks

Hi Tessa,

Could you please share some more details regarding the exact scenario you need to achieve? You want  to allow users to type only text from the items in the ItemsSource? If so this is not supported from the control - however it could be easily achieved with RadComboBox.

If you explain the scenario we would suggest the best possible solution. I'm looking forward to hearing from you.
