SilverLight DomainService XAML中在XAML中怎么给方法传参数?

public IQueryable<HarzardsInfo> GetHarzardsInfoByState(int stateId)如何在UI层的XAML中传一个int给方法
比如现在有DataGrid
<sdk:DataGrid x:Name="dgHarzardsInfo" Width="150" ItemsSource="{Binding Data,ElementName=harzardsInfoDataSource}" />
有DomainDataSource
<riaControls:DomainDataSource Name="harzardsInfoDataSource" LoadSize="20" QueryName="GetHarzardsInfoByState" AutoLoad="True">
<riaControls:DomainDataSource.DomainContext>
<ds:ForBusinessContext/>
</riaControls:DomainDataSource.DomainContext>
</riaControls:DomainDataSource>

在DomainDataSource里面怎么传参数?
<riaControls:DomainDataSource Name="harzardsInfoDataSource" LoadSize="20" QueryName="GetHarzardsInfoByState" AutoLoad="True">
就是在这里怎么传参数进去啊 QueryName="GetHarzardsInfoByState"
