RadComboBox - Use "SelectionBoxTemplate", "ItemTemplate" and "TextSearch.TextPath" properties?

[Rob]

Hello,

I am trying to use a RadComboBox with all these properties set:

<telerik:RadComboBox
    ItemsSource="{Binding TheList, Source={StaticResource DataSource}}"
    SelectionBoxTemplate="{StaticResource dt_SelectionBoxTemplate}"
    ItemTemplate="{StaticResource dt_ItemTemplate}"
    telerik:TextSearch.TextPath="Name"
    IsEditable="True"
    IsReadOnly="True"
/>

My intent is to have an auto-completable (using the "Name" property of my data object) combobox that has one template for the selected item, and another template for the listed items.  Unfortunately, when I set the "telerik:TextSearch.TextPath" and "IsEditable" properties, it seems to ignore the SelectedBoxTemplate property...

Thoughts on how I might accomplish this or if the properties will be able to co-exist in the future?

Thanks.

Hello Rob,

You are correct - when IsEditable = true, the SelectionBoxTemplate is ignored because the control displays a TextBox at the same place.

Since the template is ignored, how can we style the textbox that replaces it.  For instance, I'd like to set the HorizontalContentAlignment to Left.

Just for clarification:

<t:RadComboBox Name="KAGSubsidiaryComboBox" Margin="0,1"
                   t:TextSearch.TextPath="Name"
                   SelectedValuePath="Code"
                   SelectedValue="{Binding Path=Entity, Mode=TwoWay, NotifyOnValidationError=True}"
                   IsEditable="True"
                   Grid.Column="1"
                   Grid.Row="4" TabIndex="7" Height="24" >
        <t:RadComboBox.ItemTemplate>
            <DataTemplate>
            <StackPanel Orientation="Horizontal">
                <TextBlock FontWeight="Bold" Text="{Binding Path=Code}" />
                <TextBlock Text=": " />
                <TextBlock Text="{Binding Path=Name}" />
                </StackPanel>
            </DataTemplate>
        </t:RadComboBox.ItemTemplate>
    </t:RadComboBox>

But if the "Name" is wider than the RadComboBox, then it alligns the text to the right.

Hi Rob,

I am sorry for the delayed reply.

Note that the template has nothing to do with our RadComboBox:

<Border HorizontalAlignment="Left">
    <StackPanel HorizontalAlignment="Right" Orientation="Horizontal">
        <TextBlock Text="asda asd fasdf asd sdasd" />
        <TextBlock Text=": " />
        <TextBlock Text="asda sasdf asd fas fasfd dasd !!!" />
    </StackPanel>
</Border>

This should keep the text left aligned if there is enough space and right aligned if the text starts to clip. I would recommend you also to put Transparent background and a tooltip on the outer border so the users can read the whole thing when it is clipped.

Best wishes,

Thank you for the response.  Please find attached of the formatting that I have vs the formatting that I'd like.  Changing the content alignment etc doesn't appear to help me.

Hello Dan,

 
Please, refer to the following link in our online documentation - http://www.telerik.com/help/silverlight/radcombobox-how-to-align-to-the-left-the-text-of-the-comboboxitem-when-it-is-too-long2.html

I hope this suits your needs.

All the best,

I've read that before, but what is concerning is:  "To make it left aligned and remove the selection you can set the SelectAllTextEvent property of the ComboBox to None"

I don't want to remove the selection, my selected item should remain.  I'll try it.

--------------------------------------------

Yep, it worked... this method is less than intutive.

Does this mean it's not possible to style the displayed/selected element in an editable combobox?  I have a form where this would be ideal, I really need to be able to display a selected value AND allow the user to type-search for a new value.

A hack- override ToString() on the objects you're populating

Hi!

I need this behaviour as well, is there a chance to implement it in a future release?
greetings

Please see my last post.  It works, but it's not obvious.

Hello,

OK, I hope Dan Andrews post would help. Meanwhile I have created a PITS item for the SelectionBox template in IsEditable = True mode.
