Question

I would like to put my RowValidationRules class as a resource and then reference the Key on the datagrid but I’m not 100% sure on how to get there.

<Window.Resources><helper:AccountRoleValidationRule x:Key="MyAccountRoleValidator" /></Window.Resources>

<DataGrid.RowValidationRules><helper:AccountRoleValidationRule ValidationStep="UpdatedValue" /></DataGrid.RowValidationRules>

I would like to do something like <DataGrid RowValidationRules="{StaticResource MyAccountRoleValidator}" /> but I get ‘RowValidationRules’ property is read-only and cannot be set from markup.

In the end I’m going to use FindResource(“MyAccountRoleValidator”) from my .xaml.vb file to check the validation result on my CanSave() ICommand.

Answer 1

Try element syntax:

<DataGrid.RowValidationRules>
    <StaticResource ResourceKey="MyAccountRowValidator"/>
</DataGrid.RowValidationRules>

(StaticResource will not show up in the not so intelligent IntelliSense in VS, but when it is written out the property will)
