Customizing CollectionEditor

[AndrewRichards]

Hello,

I've encountered two bugs (or oddities) with editing collections with propertygrid's collectioneditor:

1) If the main grid in PropertyGrid can be sorted as categorical or alphabetical, then it seems than CollectionEditor is always A-Z sorted (there's no button for sorting it categorically). Is there a workaround ?

2) CollectionEditor displays collection item names using addeditem.ToString(). Is there a way to bind a child item property to be it's display name in the collectioneditor ?

Thanks!

Hello Andres,

The removal of the "sorting mode" buttons from CollectionEditor's RadPropertyGrid is by design. You can easily override this behavior by finding the RadPropertyGrid in the visual tree and setting its IsGrouped property to true. If you want do display the buttons themselves, you can modify the SortAndGroupButtonsVisibility property. As for the second inquiry of yours, we have had a few similar requests, so that we have introduces the ItemTemplate property. You can test this with our latest internal build.

All the best,

Thanks! 

Now I'm having troubles with resizing CollectionEditor (it's too small).

I can change the width of the window like this:

        <Style TargetType="telerik:CollectionEditor">
            <Setter Property="Width" Value="700"/>
        </Style>

However the left list resizes with the propertygrid in the collectioneditor..

Hi,

CollectionEditor's Template is hosted in a Grid with the following ColumnDefinitions:

<Grid.ColumnDefinitions>
<ColumnDefinition Width="2*"/>
<ColumnDefinition Width="3*" />
</Grid.ColumnDefinitions>

As both columns have relative width values it is expected for both of them to resize, when resizing occurs. You may try modifying CollectionEditor's template, by setting a hard-coded Width value for the first column, in order to override this behavior.
