WPF

I try to describe the scenario :

I’m passing a populated Dictionary<string,string> to the DomainService query to get the filtered  data.

The problem is that the data don’t get filtered in proper way if I filter by more than one parameter. The code seems to be correct. I couldn’t realize what can be the problem.




Client Side:

<pre>
Private DomainContext context = new DomainContext();
Private Dictionary<string,string> searchParameters = new Dictionary<string,string>();

Public MainPage()
{
        InitializeComponent();

        this.searchParameters.Add("ProductCategoryID","3"); 
        this.searchParameters.Add("ProductModelID","1");

        this.context.load<Product>(this.context.GetProductQuery(this.searchParameters));
}

Public IQueryable<Product> GetProduct(Dictionary<string, string> searchParameters)
{
    IQueryable<Product> queryableData = ObjectContext.Product;

    int idValue = 0;

    if (searchParameters.ContainsKey("ProductCategoryID"))
    {
        idValue = int.Parse(searchParameters["ProductCategoryID"]);
        queryableData = queryableData.Where(i => i.ProductCategoryID == idValue);
    }

    if (searchParameters.ContainsKey("ProductModelID "))
    {
        idValue = int.Parse(searchParameters["ProductModelID"]);
        queryableData = queryableData.Where(i => i.ProductModelID == idValue);
    }

   return queryableData;
}

private object _SelectedItem = null;
public object SelectedItem
{
    get { return _SelectedItem; }
    set
    {
        if (_SelectedItem != value)
        {
            _SelectedItem = value;
            RaisePropertyChanged("SelectedItem");
            itemSelected();
        }
    }
}

// Create the tree for the section
RadTreeView tree = new RadTreeView
{
    HorizontalAlignment = System.Windows.HorizontalAlignment.Left,
    ItemsSource = Clients,
    SelectedItem = this.SelectedItem,
    Name = "tvwClientProjects"
};
