Hi,

I am using XamDataGrid and I have a number of UnboundFields that have to be initialised in the code-behind.

Each of the cell in these columns binds to an instance of an object which has the following properties.

- Vol: the double value to display in the cell

- IsMin: bool

- IsMax: bool

I don't want these cell to be editable so i've set field.Settings.AllowEdit = false but it still allows the user to edit it.

I think this is because I use a control template on these cells of type XamNumericEditor to highlight the cells that IsMin or IsMax.

Is there anyway to prevent users from editing this cells?

The style I defined as is follows:

<Style x:Key="ExpiryEditorStyle" TargetType="{x:Type Editors:XamNumericEditor}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Editors:XamNumericEditor}">
<Editors:XamNumericEditor Background="{TemplateBinding Background}"
Foreground="{TemplateBinding Foreground}"
FontWeight="{TemplateBinding FontWeight}"
BorderThickness="0"
Value="{Binding RelativeSource={RelativeSource AncestorType=igDP:CellValuePresenter}, Path=Value.Vol}" />
</ControlTemplate>
</Setter.Value>
</Setter>
<Style.Triggers>
<MultiDataTrigger>
<MultiDataTrigger.Conditions>
<Condition Binding="{Binding RelativeSource={RelativeSource AncestorType=igDP:CellValuePresenter}, Path=Value.IsMax}" Value="True"/>
<Condition Binding="{Binding RelativeSource={RelativeSource AncestorType={x:Type UserControl}}, Path=DataContext.ShowHeatMap}" Value="True"/>
</MultiDataTrigger.Conditions>
<Setter Property="Background" Value="Red" />
<Setter Property="Foreground" Value="White" />
<Setter Property="FontWeight" Value="Bold" />
</MultiDataTrigger>

<MultiDataTrigger>
<MultiDataTrigger.Conditions>
<Condition Binding="{Binding RelativeSource={RelativeSource AncestorType=igDP:CellValuePresenter}, Path=Value.IsMin}" Value="True"/>
<Condition Binding="{Binding RelativeSource={RelativeSource AncestorType={x:Type UserControl}}, Path=DataContext.ShowHeatMap}" Value="True"/>
</MultiDataTrigger.Conditions>
<Setter Property="Background" Value="Blue" />
<Setter Property="Foreground" Value="White" />
<Setter Property="FontWeight" Value="Bold" />
</MultiDataTrigger>
</Style.Triggers>
</Style>
------------------------------------------------------------------------------------------------------------

[NB] I had to use XamNumericEditor as template because when I tired using CellValuePresenter, the binding failed and nothing was displayed.

Also, the reason IsMin is a property of the object I bind to is because Min is not the smallest value in the field.

It is dependent on other properties within the row. The same applies to IsMax

Thank you
