Hi, all

My page consists of a row of textboxes And a final textbox named Total

    tb1 tb2 tb3 tb4 ........ Total

Total has the sum of the values in tb1 , tb2,...

I want to dynamically calculate the value of Total each time one of the
textbox values are changed.

Presently I am handling the OnTextChanged event and it works fine but only
when the pagepostbacks

I don't want the page to postback i.e. Autopostback ="False" and still
evaluate Total Dynamically.

How can it be done ?

Hi there,

For this to work, you'll need to emit some JavaScript to the client. Add an onblur handler for each text box, that fires a client side JavaScript function. This function retrieves the values from the text boxes and then updates the Total text box.

Take a look at Page.RegisterClientScriptBlock and at the Attributes collection of a Web Control. The first allows you to send the actual function, the second allows you to add an onblur handler to the text boxes.

Cheers,

Imar

if u dont want to not postback that means u dont want to do it by ServerScripting so u have to use JavaScript as a ClientScript lang.

I am creating the textboxes Dynamically usiing the placeholder control. Can I still use the OnBlur property.

Secondly if I have <%@ Page Language ="VB" > at the start of my code , then how and where can I use JavaScript.

Of course you can. After you created your text box dynamically, simply use its Attributes collection. The control will be sent to the client, where the JavaScript will fire.

That will also answer your second question: The VB language is used to construct the page at the server; the JavaScript is sent to the client and will fire right there, in the browser.
