Hi!

I've a very simple problem but apparently GridViewDataColumn is not part of FrameworkElement and causes the MultiBinding to crash.

What I want to do is pretty simple. I have 2 'integer' columns (side by side) and I want to put a different background/border on these cells if the value inside it are not the same.

I tried that:

<telerik:GridViewDataColumn

Header="Proposed"

DataMemberBinding="{Binding ProposedQuantity, Mode=TwoWay}"

SortMemberPath="ProposedQuantity"

Width=".15*">

<local:BindingUtil.MultiBindings>

<local:MultiBindings>

<local:MultiBinding

TargetProperty="Background"

Converter="{StaticResource valuesToBackgroundColorConverter}">

<local:MultiBinding.Bindings>

<local:BindingCollection>

<Binding

Path="RequestedQuantity" />

<Binding

Path="ProposedQuantity" />

</local:BindingCollection>

</local:MultiBinding.Bindings>

</local:MultiBinding>

</local:MultiBindings>

</local:BindingUtil.MultiBindings>

</telerik:GridViewDataColumn>

I know I could simply bind on the entire object and check the 2 properties in a converter BUT what if my values are changing in code-behind???? The object will not be notified of these changes and the grid will not be updated!

Do you have a solution for this kind of problem?

Thanks,
Bastien
