TextChanged Event on Click of Other Event

Question

Hi,

  

   In my application, There is one Textbox and on textchanged event of Textbox I have written some validation code. Now my Problem is when I put text into the Textbox and directly click any other Button, first Text Changed Event get fired and then I have to Click Button Again to fire Click Event of that Button. So how do I avoid Double Click of Button.

   Any Help appreciated....

Regards,
