your filtering sample doesn't seem to work, at least not in my understanding of typing would reduce the available list items by searching either by StartsWith or Contains (which is what I need), i.e. my comboboxitems will be reduced to applicable items only as I type.

<telerikInput:RadComboBox FilteringMode="Contains" telerik:TextSearch.TextPath="Name" ....

I played with all possible combinations of IsEditable, IsFilteringEnabled, IsTextSearchEnabled - nothing seems to work as expected.

Could you please attach a code sample that works? Thanks!!

Hi
i used the Autocompletebox control in following way.

xaml:-
-------

<

 

telerikcontrols:RadComboBox x:Name="EmployeeAutoCompleteBox"  

 

IsEditable="True"  FilteringMode="StartsWith"  SelectedIndex="0" DisplayMemberPath="EmployeeDisplayName"

 

KeyDown="EmployeeAutoCompleteBox_KeyDown" Width="250" Height="23" SelectionChanged="EmployeeAutoCompleteBox_SelectionChanged"

 

 

/>
xaml.cs:-
----------

EmployeeAutoCompleteBox.ItemsSource = EmployeeCollection;                // EmployeeCollection is List in which members are Id, FIrstName, LastName.

Hope it helps you.

Best Regards,
Kiran.

Hi,

I have tried the lastest version of your demo (Q1 2010) and it seems that Kiran was right, It's currently impossible to have an editable autocomplete ComboBox.

Is it possible to add this feature ?

Thanks

Hello Yvan,

Thank you for participating in the discussion.

To have autocomplete ComboBox you will have to define the ComboBox like so:

<telerikInput:RadComboBox IsEditable="True" FilteringMode="StartsWith" />

The only thing different from the AutoCompleteBox in Silverlight toolkit is that the ComboBox doesn't expand when starting to write in the TextBox. But if you first expand it and then type in it, it behaves as expected. Is that what you mean?

Looking forward to your reply.

Hi Konstantina,

Not realy,

I want a AutoComplete ComboBox that it's not possible to enter other information than the comboxboc content but it's possible to enter the search text in the text region. I also want that the combobox list is automatiquely filtered went I type the text.

I haved try your demo (http://demos.telerik.com/silverlight/#ComboBox/Configurator ) with this properties:

• TextSearchMode = StartsWIth
•  IsFilteringEnabled = true
• ClearSelectionButtonVisibility = Visible
• CanAutocompleteSelectItems = true
• IsEditable = true
• IsReadOnly = false
• OpenDropDownOnFocus

 

But It seem that the CanAutocompleteSelectItems don't show me the first found item in the combobox text region.

I want a behavior that's not possible to enter other text than the combobox list (it's currently possible with the IsReadOnly = true but it's not possible to enter text in the combobox text region).

Thanks

Yvan

Hi Yvan,

In its current version RadComboBox cannot autocomplete when the filtering is enabled. This is something that we will change in the near future, but unfortunately I cannot promise a specific date for this feature.

By the way, the CanAutocompleteSelectItems property affects the selection of the control, not the autocomplete, e.g. when the property is true and the autocomplete completes an item, the SelectedItem/Value properties are updated. If the property is false, the values are not updated. The default value (null) switches the behavior depending on the value of the IsEditable property.

I'm working through something like this myself.  To address the issue of not allowing users to enter in anything that doesn't match the text of items in your collection.

Set IsReadOnly to True.

Hello, we are using this RadComboBox, but it seems like even if I set CanAutocompleteSelectItems="False", it sets the SelectedItem to the first matching listi tem. We need a combo box with filtering, autocompletion, but no selection on typing. 
This is what we have, we've tried all kinds of combos on those options:

<telerik:RadComboBox Name="radComboBox1" Width="Auto" 
                                 ItemTemplate="{StaticResource ComboBoxItemTemplate}"    
                                 ItemsSource="{Binding Path=Entities}"   
                                 SelectedItem="{Binding SelectedEntity, Mode=TwoWay}"                                  
                                 IsFilteringEnabled="True" 
                                 CanAutocompleteSelectItems="False"
                                 SelectionBoxTemplate="{StaticResource ComboBoxItemTemplate}" 
 EmptyText="Please select an entity..."                                
                                 telerik:TextSearch.TextPath="Name" TextSearchMode="Contains" IsEditable="True" StaysOpenOnEdit="True" 
OpenDropDownOnFocus="True" CanKeyboardNavigationSelectItems="False"/>

Hello,

I've tested the provided code and the SelectedItem is not updated while the user types in the combobox. I've attached my test page, could you please download it and give it a try?
