How to extract the name property from a selectedItem containing xml data and convert it into string.

Hello friends,

I want to extract the name property from selected item and pass it to a Elements(Xname) property,but don`t know how to convert it.Actually iam working on a filter consisting of two combo boxes and a texbox. Combobox1 is populated with selectedItem`s element(from xmldata) and combobox2 is contains selecteditem`s(xmldata) attribute.

 <ListView.ItemTemplate>
                <DataTemplate>
                    <StackPanel Orientation="Horizontal" HorizontalAlignment="Stretch" x:Name="stc" >
                        <TextBlock Text="{Binding Path=Name}" Margin="0,0,3,0" x:Name="abc"/>
                        <ComboBox Margin="0,0,3,0" x:Name="cbox1" ItemsSource="{Binding}">
                            <ComboBox.ItemTemplate>
                                <DataTemplate>
                                    <TextBlock Text="{Binding Path=Name}"/>
                                </DataTemplate>
                            </ComboBox.ItemTemplate>
                        </ComboBox>
                        <ComboBox Margin="0,0,3,0" x:Name="cbox2" ItemsSource="{Binding XPath=@*}">
                            <ComboBox.ItemTemplate>
                                <DataTemplate>
                                    <TextBlock  Text="{Binding Path=Name}"/>
                                </DataTemplate>
                            </ComboBox.ItemTemplate>
                        </ComboBox>
                        <ComboBox Margin="0,0,3,0" x:Name="cbox3">
                            <ComboBoxItem Content="Equals"/>
                            <ComboBoxItem Content="Greater Than"/>
                            <ComboBoxItem Content="Less Than"/>
                        </ComboBox>
                        <TextBox Margin="0,0,4,0" Width="50" x:Name="textbox2" />
                        <Button x:Name="but1" Height="25" Width="35" Click="click" Content="gen" />
    </StackPanel>
</DataTemplate>
</ListView.ItemTemplate>

The C# Code

 private void click(object sender, RoutedEventArgs e)
{
    try
    {
        var button = sender as Button;
        var parent = button.Parent as FrameworkElement;
        var attributebox = parent.FindName("cbox2") as ComboBox;
        var textbl = parent.FindName("abc") as TextBlock;
        var elementbox = parent.FindName("cbox1") as ComboBox;
        var combobx = parent.FindName("cbox3") as ComboBox;
        var textBox1 = parent.FindName("textbox2") as TextBox;
        XElement ele = XElement.Load(txtFileName.Text);
        var fil = from item in ele.DescendantsAndSelf(textbl.Text).Elements(elementbox.SelectedItem.ToString())
                  select item;//Attribute(attributebox.SelectedItem.ToString()).Value;
        foreach (var f in fil)
        {
            Label lb = new Label();
            lb.Content = f;
            canvas1.Children.Add(lb);
        }
    }
    catch(Exception ex)
    {
        MessageBox.Show(ex.Message,"Invalid value");
    }
}

All I want is to convert the selected combobox item to string,As i know the selectedItem properties contains object, and i want to extract the name property from the and as i cannot convert the whole object to a string....so please suggest me a way......
