Call the TextChange event for a textbox inside a datagrid

[Rattlesnake]

Hi,

I have a ASP.net 1.1 Webform that contains a datagrid , that contains 4 columns

Product--Qty--Price--Total

 

Each column has a textbox. The user will enter a value in the Product and the Qty and Price textbox. I want to call the TextChange event of the Qty and Price and textboxes whenever the text inside them changes.

In the called textchange event I want to calculate the expression Qty*Price and assign the result to the Total textbox in the datagrid.

 

How can I do this?

 

Note:The controls are in the Datagrid.
