Hi,

Same code works fine on my side. Remember that OnTextChanged event fire when textbox lost the focus ( not for each keyup/keypdown).

Thanks

Check the textbox property agin to be sure the autopostback property is set to true. you can put a breakpoint on the code behind

to be sure. i encountered same issue one time and later realised i didnt set the autopostback property of the textbox in question.

thanks
