javascript popup window and multiple parameters

[DaveyP]

I've got a gridview with a template column calling a javascript
"win.open" routine (see below).

asp code:

<asp:TemplateFi eld

HeaderText="Let ter code"

ItemStyle-HorizontalAlign =Center>

<ItemTemplate >
<asp:hyperlin k

ID=letter_code

runat=server

NavigateUrl=<
%#String.Format ("javascript:vo id(OpenPopupWin dow('letter_res ponse_detail.as px?
letter_code={0} ','width=900,he ight=450,top=47 5,left=300,scro llbars=yes,resi zable=yes'));", Eval("letter_co de"))
%>>

<%#Container.Da taItem("letter_ code")%>
</asp:HyperLink>

</ItemTemplate>

</asp:TemplateFie ld>

/asp code

Code for the routine is :

<script language="javas cript">

function OpenPopupWindow (target_url,win _options)
{

Window.open(tar get_url,null,wi n_options)retur n false
}

</script>

This works fine. The problem that I have, is that I now need to call
the popup with two extra parameters which are taken from 2
dropdownlists elsewhere on the form.

Suggestions as to how I do this?

Cheers

There is no Window object in Javascript, it's named window. Javascript
is case sensetive.

Don't use null as window name. Use '_blank' if you want to open a new
window.

You have forgotten the semicolon between the statemenets.

}

Do you want to take the values at the time of creating the page, or when
the user clicks the link?

For the first, you would add parameters in the String.Format, and append
the url in the format string with "&{1}&{2}".

For the second, you would add the values in the javascript. Perhaps
creating a new function if you don't want to change the OpenPopupWindow
function.
