GridViewComboBoxColumn different dropdown/selected values

I have a GridViewComboBoxColumn inside a RadGridView. The GridViewComboBoxColumn is bound to a collection of Objects. I need to display different things for the selected option vs the dropdown options. I would like to display one property of the Object in the selection box (object.Name), and another property in the drop down (Object.Description).

I accomplished this in a RadComboxBox before by doing the following:

<telerik:RadComboBox Grid.Row="2" Grid.Column="1" telerik:StyleManager.Theme="Windows8Touch" Margin="5 3 5 0" MaxDropDownHeight="1000"

ItemsSource="{Binding MultiCropTypes}" SelectedValue="{Binding SelectedMultiCropTypeId, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=True}"

Tag="{Binding MultiCropTypes}" SelectedValuePath="PkMultiCropTypeId">

<telerik:RadComboBox.SelectionBoxTemplate>

<DataTemplate>

<TextBlock Text="{Binding Description, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}" TextTrimming="CharacterEllipsis" />

</DataTemplate>

</telerik:RadComboBox.SelectionBoxTemplate>

<telerik:RadComboBox.ItemTemplate>

<DataTemplate>

<TextBlock Text="{Binding Name, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}" TextWrapping="Wrap" Width="900" Margin="0,0,10,0" />

</DataTemplate>

</telerik:RadComboBox.ItemTemplate>

</telerik:RadComboBox>

I can't do this for a GridViewComboBoxColumn because there is no "SelectionBoxTemplate" property.

Is it possible to get the same behavior in a GridViewComboBoxColumn? Any help would be greatly appreciated. Thank you.

Use Aggregrate Functions with AutoGenerateColumns set to True

Hello,

Is it possible to use the AggregateFunctions CountFunction with AutoGenerateColumns set to True? We have a datasource we would like to connect to without defining each columns in xaml or code. In every example I've always seen the AutoGenerateColumns set to false. As it stands, if I do the same I will either endup with a "blank" column or duplicate.

Kind regards

DataForm + RichTextBox sample

Hi, I was wondering if there is a sample for the integration of RichTextBox in a DataForm?
I would like to use the RichTextBox as a replacement for a "normal" TextBox in a dataForm.

<telerik:DataFormDataField DataMemberBinding="{Binding Description, Mode=TwoWay}"

Label="Description:"

IsEnabled="True"

IsReadOnly="False"

Description="You can enter any information regarding this server in this field.">

<telerik:DataFormDataField.Content>

<telerik:RadRichTextBox x:Name="rtbDescription" Width="450" Height="200"></telerik:RadRichTextBox>

</telerik:DataFormDataField.Content>

</telerik:DataFormDataField>

I understand I'll have to capture certain events to keep the RichTextBox's document in sync with the bound property, and work with a FormatProvider to import/export the RichTextBox document into/from that property.

However, A sample would be much appreciated.

Thanks a lot

How to implement a custom layout algorithm?

We need to create a custom layout algorithm class to be used for laying out nodes. I suppose a certain class needs to be derived, adding necessary logic to handle events such as "new level" etc. Do you have a sample app that demonstrates this technique?

The major reason for our need for a custom layout algorithm is that your algorithms fail for most trees when using custom nodes. It's usually something like 90% correct, but that 10% looks really awful.

More about this issue here:
http://www.telerik.com/community/forums/wpf/diagram/treedown-layout-not-working-for-custom-nodes.aspx

This is what we have now:

var layoutSettings = new TreeLayoutSettings()

{

TreeLayoutType = Telerik.Windows.Diagrams.Core.TreeLayoutType.TreeDown,

HorizontalSeparation = 50d,

UnderneathVerticalTopOffset = 50d,

UnderneathHorizontalOffset = 80d,

ComponentsGridWidth = 2000d,

UnderneathVerticalSeparation = 100,

AnimateTransitions = true

};

this.treeLayout.Layout(this.diagram, layoutSettings);

Result: See treedown.png.
Wanted: See treedown_extended.png

UPDATE: Why not just give us the source code of TreeLayout.cs. That would help a lot!
