DIV onclick postback - how to identify on the server side?

Chris Buckett9-Jan-07 22:40

Can anyone help with this?

I have an aspx page with 2 divs both marked to run at server.

<div id="div1" runat="server">
    this is div 1
</div>
    
<div id="div2" runat="server">
    this is div 2
</div>

In the page load, I dynamically add a clientside onclick postback to the divs like so:

if (!IsPostBack)
{
  div1.Attributes.Add("onclick", 
     Page.ClientScript.GetPostBackClientHyperlink(div1, ""));
  div2.Attributes.Add("onclick", 
     Page.ClientScript.GetPostBackClientHyperlink(div2, ""));
}

When I click on the div it postbacks ok, but the question is, how do I identify on the server which div sent the postback? (or have I got the wrong end of the stick)?

Cheers

Hi Chris:

Here is just a suggestion...Before do postback, you store div id into a hidden field...then you can parse this at server side to know which div causes post back...

Hope you get the clue...

At the server side, you simply check on the Request.Form["__EVENTTARGET"] entry to see which object causes the postback, for example if you click the div 1 then the value should be "div1". In addition, you might think about building a custom div control with a custom event, say Click, and you can easily determine which div causing the postback using the sender object of the Click event handler.

Try and write your Validation code in the onValidating event of cell such that if it doesnt validates, cancel (e.cancel=true) the effect so that cursor remains within the same cell.

Ok Thanks very much but I find other solution more easy, I used the comparevalidation object and put in type "double" this solution is simple and perfect, now only permited number and dot.
This information I found in this foro. Thanks.
My little problem is that I not understand the format of custom validation expression and I not find information about this.
Thanks very much.

Make sure that the link in the address bar points to your current page. If you have done something like a Server.Transfer to get to the current page, then the link will show the old value.

the last thing I want to see is some pasty-faced geek with skin so pale that it's almost translucent trying to bump parts with a partner - John Simmons / outlaw programmer

The problem comes from the way that IE renders the listboxes - they do not really work with things like z-index. A workaround is to 'shim' an iframe underneath the div tags that you are rendering to form the menu. See here[^] for details.

You need to create that new row in the datasource for that grid and then rebind the grid.
