ASP.NET is a framework for writing web applications. It contains nothing that could be used to read Excel files.
ADO.NET (the framework for interacting with databases) may have some mechanism for dealing with Excel files.
You can also interop with Microsoft office through COM in order to access files.
Finally, Office 2007 documents use a new file format that consistes of XML files in a zipped file (change the .xlsx file extension to .zip and you can open it and see what's inside).

you can also use linq. read the file in from the disk or memory stream and you can query it.

Really clever this LINQ stuff, isn't it? I'm told it can bring world peace and stabalise the global economy too!

*grin* I guess I better start using it, no matter what the specifics of my project, then.

Well, you plainly can't do this with ASP.NET, you surely know that ? You can host a web browser in a C# forms program and from there write code to do the postback that pushes the button.

When I want to load an RSS file using its URL, below error will be appeared:
A socket operation encountered a dead network [IP Number]
Maybe the problem is because of using a proxy server for internet connection. I've used Isa-Server to connect to internet. So I tried to use NetworkCredential but it can't solve the problem:
System.Net.NetworkCredential networkCredential = new System.Net.NetworkCredential(myUserName, myPassword, myDomain);
XmlUrlResolver xmlUrlResolver = new XmlUrlResolver();
xmlUrlResolver.Credentials = networkCredential;
XmlReaderSettings xmlReaderSettings = new XmlReaderSettings();
xmlReaderSettings.XmlResolver = xmlUrlResolver;
XmlReader xmlReader = XmlReader.Create(txtRssUrl.Text.Trim(), xmlReaderSettings);
How can I load an RSS file using its URL?

What is not working ?
You need to add this three thing on GridView1_PageIndexChanging events
GridView1.PageIndex = e.NewPageIndex ;
GridView1.DataSource = Ds;
GridView1.DataBind();

Hi all,
I am using this code on aspx page from where i open model window:
function AddValue(Param)
{
var winSettings = 'center=yes,left=150px,top=150px,status=yes,scrollbars=yes,resizable=yes,width=300,height=300';
var Status=window.showModalDialog('/Scheduling/View/DataInput/AddPopup.aspx?Key='+Param,'',winSettings);
document.getElementById('ctl00_CPHMain_hdnCheck').value=Status;
document.getElementById('ctl00_CPHMain_hdnKey').value=Param;
if(Status==1)
{
return true;
}
else
{
return false;
}
}
and using this code on model window:
function CloseWindow(returnValue)
{
window.returnValue =returnValue;
window.close();
}
calling this function for returning value while closing window:
<asp:ImageButton ID="btnSave" runat="server" OnClick="btnSubmit_Click" CausesValidation="true" ToolTip="Click here to Save" SkinID="save" > </asp:ImageButton>
<img src="../../App_Themes/White/Images/btn_cancel.jpg" alt="cancel" onclick="CloseWindow(0);" title="Click here to close window" id="IMG1" />
Now problem is that when i click on image which is use for cancel then it close with return value 0 but at the time of saving when i click on image button for saving its looks llkes as other window is open and close after saving but this model window remains same.
On mozilla its working well but on ie7 i m getting this problem

That's because you are doing a postback in a modal window. (That's "modal", not "model"...) You can't post a form to a modal window, that is why it opens in a new window.
If you want a modal window and want to make a postback, open a frameset page in the modal window that contains a frame that opens the page. That of course means that the returnValue property is in the frameset page, i.e. the parent of the page in the frame.
Despite everything, the person most likely to be fooling you next is yourself.

but this problem is not occurring in mozilla,why so
