Hi Cheryl,
you can achieve this by opening a model window through
some javascript in the main page, then calling a function
in the original page from the new window when the ok
button is clicked that processes the data from the modal
window.
The original page can process the modal form data using
javascript with the example below, but you can extend
this to process the data server side by forcing a
postback.

Here's a code example:

[Modal Window - ModalWindow.aspx] [C#]
function ModalButtonClick()
{
if( window.dialogArguments )
window.dialogArguments.ProcessModalData
(dropdown1.value,dropdown2.value,dropdown3.value);
window.close();
}

<SELECT id='dropdown1'>
//additional dropdownlists rendered here
<INPUT type=button onclick='ModalButtonClick();'
value='submit'>

[main page] [C#]
function ShowModalWindow()
{
window.showModalDialog
('ModalWindow.aspx',this,'dialogWidth:400px;dialogHeight:2
00px;center;help:no;Yes;resizable:yes;status:no;scroll:no'
);

}

function ProcessModalData(string1,string2,string3)
{
//javascript to do something with the form data
passed in here
}

Hi alex,

I am new in both javascript and asp.net. After putting in the code, I
have encountered this error msg, "Object doesn't support this property or
method"
on "window.dialogArguments.ProcessModalData
(dropdown1.value,dropdown2.value,dropdown3.value);" . And does not know what
when wrong.

And I got another problem, after the form data have passed back to the main
page. How am I going to get the data and place it on the datagrid.


Thanks
