Hi.. I have the following. The autocomplete does not work unless the Combo dropdown is open. Any ideas why. How can get the autocomplete to work when the Combo has focus.. thanks again for your help.

  <telerikPresentation:RadComboBox  TabIndex="4" Height="54"  Name="cmbCustomer" TextSearch.TextPath="cust_name" Style="{StaticResource requiredFieldValidationStyle}"  SelectedIndex="0" SelectedItem="{Binding cust_name, Mode=TwoWay}" SelectedValue="{Binding Path=cust_name}" SelectedValuePath="cust_name" Width="332" >

                    <telerikPresentation:RadComboBox.Effect>

                        <DropShadowEffect BlurRadius="0" ShadowDepth="2" />

                    </telerikPresentation:RadComboBox.Effect>

                    <telerikPresentation:RadComboBox.ItemTemplate>

                        <DataTemplate>

                            <Grid Margin="5" Width="300">

                                <Grid.ColumnDefinitions>

                                    <ColumnDefinition />

                                    <ColumnDefinition />

                                    <ColumnDefinition />

                                </Grid.ColumnDefinitions>

                                <Grid.RowDefinitions>

                                    <RowDefinition />

                                    <RowDefinition />

                                    <RowDefinition />

                                </Grid.RowDefinitions>

                                <TextBlock FontWeight="Bold" x:Name="txtCUST_NAME" Grid.ColumnSpan="2" Text="{Binding cust_name}" />

                                <TextBlock Foreground="Navy" Grid.ColumnSpan="3" Grid.Row="1" Margin="10,0,0,0" Text="{Binding address}" />

                                <TextBlock Foreground="Navy" Grid.Column="0" Grid.Row="2" Margin="10,0,0,0" Text="{Binding city}" />

                                <TextBlock Foreground="Navy" Grid.Column="1" Grid.Row="2" Margin="0" Text="{Binding state}" />

Hello Jon,

When the control is not Editable (IsEditable=false) you have to type the complete text of the item in order to select it when the drop-down is closed. When IsEditable = true, the autocomplete should select partial matches (without the need to type the complete text) even if the dropdown is closed.

In my code.. if I set IsEditable = true.. the combo box show the object it's bound to... and nothing else

"   Object.Customers"

The ItemTemplate doesn't appear to work and the autocomplete does not work...

Any ideas?

thanks again

Hi Jon,

I just noticed that you are using the standard TextSearch.TextPath attached property. Please, try with telerik:TextSearch.TextPath - this should fix the problem. We will make sure that the control works with both attached properties in one of the upcoming builds.

Hello,

I found that the auto-complete feature selects the first partial match.

In my application, if a user types "A", all items starting with "A" should get listed and not the first item starting with "A" should get selected.

I am essentially looking for autocomplete + filtering kind of thing.

Is that possible with telerik wpf combo box ?

Please let me know

Thanks,
Ashish

Hello Ashish,

Thank you for your participation in the conversation.

This behaviour of the autocomplete of the ComboBox is by design. You can find more information about autocomplete feature of the ComboBox in this help article and for filtering you can refer to this one.

If you need further help please let us know.

Kind regards,
Konstantina
