Treecontrol: SelectionChanged Event called thrice
<p>I have a tree control used in my form and have around 10 items in the tree. 
Each Parent having one sub child/node. </p>

<p>I am handling the SelectionChanged event of the tree. Whenever an treeitem is selected this event is fired and the function called. But this function is called at least thrice!! </p>

<p>Is there something that i have done wrong where everytime i select a tree item it is called thrice !! </p>
