Hi,

Please have a look into the following code snippet to achieve your scenario.

ASPX:

<telerik:RadDropDownTree ID="RadDropDownTree1" runat="server" AutoPostBack="true"
    DataSourceID="SqlDataSource1" DataTextField="text" DataFieldParentID="parentid"
    DataFieldID="id" OnEntryAdded="RadDropDownTree1_EntryAdded">
</telerik:RadDropDownTree>
<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="true" Visible="false">
</telerik:RadGrid>

C#:

protected void RadDropDownTree1_EntryAdded(object sender, Telerik.Web.UI.DropDownTreeEntryEventArgs e)
{
    String connstring = WebConfigurationManager.ConnectionStrings["NorthwindConnectionString"].ConnectionString;
    SqlConnection conn = new SqlConnection(connstring);
    SqlDataAdapter adapter = new SqlDataAdapter();
    adapter.SelectCommand = new SqlCommand("SELECT * from Details WHERE text LIKE '" + e.Entry.Text + "%'", conn);
    DataTable data = new DataTable();
    conn.Open();
    try
    {
        adapter.Fill(data);
    }
    finally
    {
        conn.Close();
    }
    RadGrid1.Visible = true;
    RadGrid1.DataSource = data;
    RadGrid1.DataBind();
}

Let me know if you have any concern.
Thanks,
Shinu.
