Hi,
I want to use a gridview to insert student grades for a module (total area unknown) for this i use a dynamic query and I display the gridview
Number students ___subject 1____subject2 ....( subjects of a module) but I can not put the gridview in edit mode ,how do that?
I searched on google but most of the gridview it already knows the number of column so we do not use autogenratecolumn=true which facilitates edit mode and insert the gridview data in the database.
Thanks.

I am quite new to Javascript and this question probably would seem very basic, but I am really stuck. I have a button. When I click it, the Javascript should cause an alert to display "hello" to the screen. When I build the project I get the error:
'ASP.default_aspx' does not contain a definition for 'Hello' and no extension method 'Hello' accepting a first argument of
type 'ASP.default_aspx' could be found (are you missing a using directive or an assembly reference?)
Aspx:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!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>Test</title>
<script type="text/javascript">
function Hello() {
alert("hello");
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Button ID="Button1" runat="server" Text="Button" onClick="Hello()"/>
</div>
</form>
</body>
</html>

Change it to OnClientClick="Hello()"
OnClick set like you have it will attempt to call a server side function, i.e. your code behind. Which ain't there! Hence the error makes sense.

here;
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebApplication1.WebForm1" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<body>
<form id="form1" runat="server">
<div>
<input id="Submit1" type="submit" value="submit" onclick="return Hello();" />
</div>
</form>
</body>
<script type="text/javascript" language="javascript">
function Hello()
{ alert("Hello"); }
</script>
</html>

It's just the difference between using a standard html button or an asp.net server button. A button with runat="server" behaves very differently than a normal html button.

You see this form is supposed to run on server side. So it'll try to call procedures on the server and not the client. If you want to perform this task, you have some options like:
write a function in C# on server side like this
public void Hello()
{MessageBox.Show("Hello World")}
or do not use an asp button. Use HTML button like
<input type="button" onclick="Hello()" />
or as said by somebody above, you can use onClientClick event handler..
Hope this will clarify all your doubts

Hi
I'm just curious about something. I've recently been playing around with WebRequests and WebResponses. I create a request like so:
WebRequest someRequest = WebRequest.Create("https://blah.blahblah.com/blah/");
Then I retrieve the response stream of that request like so:
Stream objStream = someRequest.GetResponse().GetResponseStream();<br />
StreamReader objReader = new StreamReader(objStream);
This basically returns something like the following:
<div id="main"><div class=header>
<a href='https://www.google.com/accounts/'> <img class=logo
src='https://www.google.com/intl/en/images/logos/accounts_logo.gif'
alt="Google" /> </img> </a></div>
<div id=maincontent>
<table border="0" width="100%" cellpadding=0 cellspacing=0> <tr>
<td width="75%" valign="top"> <div style="font-size:83%;">
<b> A third party service is requesting permission to access your
Google Account.</b><br/><br/>
In order to authorize a third party service to access your account,
you must sign in.</div> </td>
<td style="padding-left: 10px; " valign="top" align="center">
<div id="rhs"> <div id="rhs_login_signup_box">
<script><!--function gaia_onLoginSubmit() {
if (window.gaiacb_onLoginSubmit) { return gaiacb_onLoginSubmit(); } else {
return true; }}--></script><style type="text/css"><!--
div.errormsg { color: red; font-size: smaller; font-family:arial,sans-serif; }
font.errormsg
It basically contains all the website controls etc. My question is, lets say this specific website has a username and password field, is there any way I can edit the above response to navigate my web browser control to the website, populate the username and password boxes and log the user in?

hi,
am using menu.js to build a menu in an aspx page and am also using prototype.js in the same page and i well know that the use of prototype.js before that menu leads to display the menu in a wrong way in Opera browser where as it work well with IE & Firefox browsers. i need to resolve this with Opera browser inorder to display the menu in a right way as it is shown in other browsers.
Ref Url: http://www.itifsl.cmlinks.co.in/Insurance/Index.aspx.
Kindly help me in getting this problem solved. Thanks in advance.
Regards,
Jayakrishna

Looks like you need to handle the CSS of the menu based on the browser. Keep the current display stylesheets for IE & Firefox but have a different one for Opera. You can go for two css classes and refer them based on the browser.

Store the identity of the selected node in a session variable, perhaps?

You need any of the state management techiniques that suits your application, Session/Basepage property being the best ones. Other's can be QueryString, HiddenField in basepage, Cookie, BasePage Property.

Thank for your reply.
Do you mean to run that exe?
|
|
|
|
|
Open Visual Studio Command Prompt and run that tool with the required arguments. Can you check that link that I've provided in the previous post

@Arun Jacob : Thank you for your suggestion ...
Can fixed that problem now.
By runing "aspnet_regiis - i" form right version.
First time I did a wrong choice for version, I choose "aspnet_regiis.exe" from v2.0.50727 and run.
Actually I am using version 4.0.
After re-running "aspnet_regiis -i" from v4.0.30319 everythings going smoothly.
Pls, don't mind me for long explain unnecessary, I just mean to people who face this problem in future. Just inform them to do right choice.
Thanks and Best Regards

hi,
how can be known that the pics in the iis server is accessed from other sites?The image from another site get rendered from oursite.Do i have to give the image path from the page ?

This article should point you in the right direction.
generating-asp-net-images-fly
Ignore the parts about generating the image but if you look at Response.ContentType and the way to link to the image this should let you create an aspx page in which you can save request details to a database and then send your image to the client browser.

Hi,
try to take a look at the following topic: linked servers. With them you can access excel files like a database. Every sheet is its own table.
Alternatively you can try to read the file using oledb-driver or ADO.Net
