I don't think you can display excel file in modal dialog. Can't you use window.open() instead of window.showModalDialog() ?
If you need to use modal dialog, then put an iframe in your modal dialog page:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="ModalDialogPage.aspx.cs" Inherits="ModalDialogPage" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Excel export</title>
<link type="text/css" rel="Stylesheet" href="ModalDialogPage.css" />
</head>
<body>
<form id="form1" runat="server">
<div>
<iframe name="excelExporter" src="excelExporter.aspx"></iframe>
</div>
</form>
</body>
</html>
note stylesheet file modalDialogPage.css:
body
{
margin:0px 0px 0px 0px;
padding:0px 0px 0px 0px;
border: none 0px #000000;
width:100%;
height:100%;
}
iframe
{
margin:0px 0px 0px 0px;
padding:0px 0px 0px 0px;
border: none 0px #000000;
width:100%;
height:100%;
scrolling:no;
frameborder ;
}
and then you can put your excel generating code into your excelExporter.aspx page.
should be working!

I didn't completely understand what you are saying. But here is the problem I am facing. In the popup window I have the tag <base target="_self" />. THis tells the browser to display the results in the same window instead of opening in a new window. So when I do the export to excel it is not able to display the save/open dialog because of that. If I remove that tag, it is able to display that dialog but the problem is everytime I do a postback it opens the new window to display the results.
Thanks,
sridhar.

I have figured the solution for this. I have added onclick event to the excel button. The onclick event will open a new window using window.open method. In that new window I have the code that exports the data to excel.
Thanks,

Hi,
Your parameter "@docContent" its datatype should be OdbcType.Binary or OdbcType.VarBinary.
Coz these two datatypes are mapped to an array of Byte.
I hope this will help you.
Thanks and Regards,

I have changed that error you have pointed out but I still get the same error message. The change from Odbctype.Text to OdbcType.Binary had been made for @docContent and still VS2003 throws the same exception. I don't know what else to do, all of the other variables have been checked for invalid type
casting and I don't see any. Please help me spot the error. Thank you in advance for your help.

Hi,
R u getting the same error at the same line as previous one?
Thanks and Regards,
Chetan Ranpariya

|

Yes, I get the same error message as before. I even tried changing Binary to VarBinary and that didn't help either. Please take at look at my code for me to see where the problem is. VS2003 says it's the line that says cmdInsert.ExecuteNonQuery() that is causing the problem and it marked that line red. Is there anyway that you can run my code to see where the problem is? Please help me solve this problem, I ran out of ideas. Thanks again for your time.

RadioButtonList.item.add(b);
RadioButtonList.item.add(c);
RadioButtonList.item.add(d);
RadioButtonList.item.add(e);
Similarly , i want to add item in RadioButtonList using java script.

What method do you think is better when there are many threads?

You can't do that. The RadionButtonList control doesn't exist in the browser, it only exists on the server while the page is created.
As what you are asking for is impossible, what is it that you want to accomplish?

single minded; short sighted; long gone;

You cannot do as how you have stated for the Radio Button list.
Since the Radio buttonlist control exist on the server side while the page is creatred this method is impossible.
so go with the method as how i have stated before.

Satips.

One option is to enumerate the subkeys of
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Time Zones
