QuestionWPF DataGridCell Binding Problem Pin
Kevin Marois7-Apr-22 14:39
professionalKevin Marois7-Apr-22 14:39 
I have a DataGrid bound to a list of models. On the ViewModel is a property called AreFieldsEnabled. When the user clicks Edit the it sets AreFieldsEnabled to true and the datagrid becomes enabled/

I have this style
<Style x:Key="dataGridCurrencyCellStyle" 
        BasedOn="{StaticResource dataGridCellStyle}"
        TargetType="{x:Type DataGridCell}">

    <Setter Property="Width" Value="75"/>
    <Setter Property="TextBlock.TextAlignment" Value="Left"/>
    <Setter Property="TextBlock.Text" Value="{Binding StringFormat=C}"/>
    <Setter Property="IsEnabled" Value="{Binding DataContext.AreFieldsEnabled, ElementName=budgetControl}"/>

</Style>

What I need do now is a change it to a MultiTrigger. On the model is a bool property called IsCellEnabled which I set programmatically when loading the data.
<Style x:Key="dataGridCurrencyCellStyle" 
        BasedOn="{StaticResource dataGridCellStyle}"
        TargetType="{x:Type DataGridCell}">

    <Setter Property="Width" Value="75"/>
    <Setter Property="TextBlock.TextAlignment" Value="Left"/>
    <Setter Property="TextBlock.Text" Value="{Binding StringFormat=C}"/>
    <Setter Property="IsEnabled" Value="False"/>

    <Style.Triggers>
        <MultiTrigger>
            <MultiTrigger.Conditions>
                <Condition Property="AreFieldsEnabled" Value="True" />
                <Condition Property="IsCellEnabled " Value="True" />
            </MultiTrigger.Conditions>
            <MultiTrigger.Setters>
                <Setter Property="IsEditing" Value="True" />
            </MultiTrigger.Setters>
        </MultiTrigger>
    </Style.Triggers>

</Style>

Now, both conditions are wrong and won't compile.

So, the AreFieldsEnabled property is on the ViewModel. The IsCellEnabled property is on the Model bound to the grid.

What's the right way to do this?
If it's not broken, fix it until it is.
Everything makes sense in someone's mind.
Ya can't fix stupid.
