Filtering problem at openaccesslinqdatasource with my treeview's Checkedvalues(multiple selection).

[Cuneyt]

Hi. first i am sorry because of the this long message.
there is a treeview,  button and listview. when i hit button listview's datasource should be filtered with treeview checked values.

 treeviewKat
(
CheckBoxes=true,
CheckChildNodes=true,
TriStateCheckBoxes=true
)
and  I am filtering an OpenAccessLinqDataSource with this treeviewKat's checked values.

How can i filter to OpenAccessLinqDataSource with treeviewKat's CheckedValues (multiple values).
 
I tried to add every node.value in the nodecollections of checked nodes to linqdatasource. but i cant get result.

Taking node.value of treeview is correct. i can see true added OADLSSoruTV.whereparameters, but i cant see listview update (lvSoruTV).

code-behind below:

protected void RadButton2_Click(object sender, EventArgs e)

        {

            OADLSSoruTV.WhereParameters.Clear();

  

            IList<RadTreeNode> nodeCollection =
                  treeviewKat.CheckedNodes;



            foreach (RadTreeNode node in nodeCollection)

            {

               

                OADLSSoruTV.Where =
                        "KategoriId ==Int32?(@KategoriId)";

                OADLSSoruTV.WhereParameters.Add
                        (
                          "KategoriId",
TypeCode.Int32,

node.Value.ToString()
                        );

     }

                OADLSSoruTV.DataBind();
}

Adding parameter OADSSoruTV is correct because i tried same thing with dropdownlist instead of treeview and it is working good.
