Dynamic calculation using databinding and Autopostback property

[jagdishl]

Hi:
I have a form in which the total is calculated dynamically(without
using a submit button) based on the inputs given in the text box
fields.
I had bound the total textbox control using the custom binding
expression


system.convert.toDouble(txt0to30dayscosts) +
system.convert.toDouble(txt31to60costs) +
system.convert.toDouble(txt61to90costs) +
system.convert.toDouble(txt91to120costs) +
system.convert.toDouble(txt120daysovercosts) +
system.convert.toDouble(txtprecosts)


I had also set the Autopostback property "True" for each of these
textbox controls.Yet this does not seem to work,I would really
appreciate if someone would help me on this.
Thanks

Jagdish,

First, where is this code located. You have to put it in TextChanged event
handler function for each textbox.

Second, TextChanged event will on raise when focus moves out of the textbox
control.

The better way to do is write JavaScript code to update Total on the client
side without having to postback.
