Hell all,

I am developing application in ASP.NET, the challenges arise when my user enter data's into the asp:TextBoxes as the TextBox loses focus a Summary TextBox sum all the datae before saving.

if their is a wrong entry in some of the asp:TextBoxes, since asp;TextBoxes only allow _TextChanged event therefore any change made on the TextBoxes will not affect the summary TextBox, i tried the following trick:

this work once sine then it not working again.

"OnTextChanged" event trigger after change complete, that's means this event will trigger when textbox is lost focus.

You can try using javascript "onchange" event. This event trigger after every key press.
