Change DataGrid row background based on current item.Status

[sn4k3]

I would like to change the background of entire row based on row item.Status, to be Red when is failed and null when success. Due this I can't use the one time OnRowLoading event. Is there any alternative?

If not possible I think the alternative would be set the text in Red. Are two TextBlock with different classes and IsVisible the best way to do the class change?

This could do it:

<DataGrid ...>
    <DataGrid.RowTheme>
        <ControlTheme
            x:DataType="vm:YourItemType"
            BasedOn="{StaticResource {x:Type DataGridRow}}"
            TargetType="DataGridRow">
            <Setter Property="Background" Value="{Binding Status, Converter={StaticResource StatusToRowColorConverter}}" />
        </ControlTheme>
    </DataGrid.RowTheme>
</DataGrid>

Docs about making a custom converter here. (I made up StatusToRowColorConverter, you'd have to implement that yourself)

If your viewmodel object is observable and property Status raises a PropertyChanged the DataGridRow will respond to it.

The BasedOn is giving trouble

I tested this xaml in avalonia's ControlCatalog app, in there it works in runtime. You are including a base ControlTheme for DataGridRow in your resources?

That was it, I was not including DataGrid style because i'm using an external UI theme, looks like they lack that resource, I will check.
Applying default theme worked with your sample, thank you!
