Memory consumption of WPF application in TaskManager

Hi there,

I am doing a WPF application. When I am running the application and check for the Memory consumption in TaskManager, it is getting gradual increase when we do some operations. I am messed up whether this is the behavior of WPF controls or I did something wrong.

Let me say an example:
I am having two textboxes that contains some values and two buttons.
When I click one of the button, the value of 1st TextBox copied to another. And on click of another button, the reverse (copying from 2nd to 1st) happens.
On each every click the Memory consumption increases. (The case includes ListBox, etc.,..
Please give me some assistance.

The CS code as follows.

private void button1_Click(object sender, RoutedEventArgs e)
{
ListBoxItem item = (PinnedListBox.SelectedItem as ListBoxItem);
PinnedListBox.Items.Remove(item);
UnPinnedListBox.Items.Add(item);
}

private void button2_Click(object sender, RoutedEventArgs e)
{
ListBoxItem item1 = (UnPinnedListBox.SelectedItem as ListBoxItem);
UnPinnedListBox.Items.Remove(item1);
PinnedListBox.Items.Add(item1);
}

Thanks in advance
