Maybe you have an issue with the flash plugin in IE? Maybe it isn't installed in IE?

I am using ItemDataBound event to add a Link button to a column using following code
LinkButton temp = new LinkButton();
temp.Click += new EventHandler(xyz);
temp.ID = e.Item.Cells[i].Text;
temp.CommandArgument = e.Item.Cells[i].Text;
temp.Text = e.Item.Cells[i].Text;
now when page is displayed i see these buttons but when i click on them, page is refreshed but Click event is not raised. how can i see which event control and which event is raised when i am clicking this link.
Regards
Shajeel

when u click it only page_load raised.
i think that you'r plused event is null or empty.
if u add your event in page load each time there will be right.

Datasets don't contain rows or columns. Datasets contain tables, and the tables contain rows and columns.
You could perform the transposition in code, creating the output table dynamically by adding the required rows and columns.

Hi All,
There is the requirement to read Excel file and store data in a datatable for my web project. I am using C# language.
My code is written below
String connString = "Provider=Microsoft.Jet.OLEDB.4.0;" +
"Data Source=" + excelFile + ";Extended Properties=Excel 8.0;";
objConn = new OleDbConnection(connString);
objConn.Open();
OleDbCommand objCmdSelect = new OleDbCommand("SELECT * FROM [" + excelSheetName.Trim() + "]", objConn);
OleDbDataAdapter objAdapter1 = new OleDbDataAdapter();
objAdapter1.SelectCommand = objCmdSelect;
objAdapter1.Fill(dt);
The above code returns data to a data table, but the problem is to read formated Excel sheet. Suppose there is a formula field, it doesn't store the actual value. It stores some different value.
What other method to read the excel file? I am not using COM component of Excel to read as it is a web project. There may be a security problem after deployment. 
Thanks in Advance. :

I am starting work on an web application that has the possibility of morphing into three distinct sites, an intranet, an extranet, and finally a website in the company's dmz. All three sites would access parts of the same database. What I want to do is to develop a central solution that contains all the common class libraries and handles all communication with the database.Then I would build a separate solution for each of the sites.
I have seen a similar scenario at a client I was not part of the development team and I'm not sure where to start, or how I would go about communicating with the central solution from any of the others.
I would really appreciate any pointers to get me started, the names of any books that would help, or any tutorials that deal with something of this scope.
Thanks.

So, I posted over on the MS as.net forums, but I have to wait for moderator approval for the post to show, and frankly - I'd rather not wait.
I've been googling all over the net and not found an answer that I can completely understand -- heck I'm not even sure I have been googling the right terms.
I need to pass the contents of a DataSet to an ImageButton EventHandler function. The code I have right now errors cuz I believe the standard EventHandler doesn't allow arguments. I found some info on custom EventHandlers, but I don't really understand how to implement them. Here is the pertinenet code:
C# Script tag code:
<br />
public void exportClick(DataSet dat)<br />
{ <br />
DataTable dt = dat.Tables[0];<br />
DateTime dateStamp = DateTime.Now;<br />
string file = dateStamp.Hour.ToString() + dateStamp.Minute.ToString() + dateStamp.Second.ToString();<br />
CreateCSVFile(dt, Server.MapPath("/csv_export/export"+file+".csv"));<br />
}<br />
sql = "SELECT......";<br />
dat=readDb(sql);<br />
<br />
ImageButton ib = new ImageButton();<br />
ib.ID = "exportButton";<br />
ib.ImageUrl = "./img/export.png";<br />
ib.Width = 110;<br />
ib.Height= 25;<br />
ib.AlternateText="Export to CSV";<br />
ib.Click += new EventHandler(exportClick(dat));<br />
Panel1.Controls.Add(ib);<br />
And the HTML:
<br />
<body><br />
<form runat="server"><br />
......<br />
<asp:panel id="Panel1" runat="server" height="25px" horizontalalign="right" /><br />
......<br />
</form><br />
</body><br />
So ideally what should happen is that the user clicks on ImageButton "ib", which fires the exportClick(dat) function and a CSV file is created from the DataSet "dat". If I can get this working, I have code to fire a file download of the CSV that will get stuffed in as well, but I deal with that once I have a CSV.
Thanks in advance!

I'm not sure I agree with the logic of your approach. Wouldn't it be better to build the CSV file after the user has clicked the 'Export' button? After all, if the user doesn't click the button then the effort of fetching the data and building the file has been wasted. I would create the file when the user chooses to export the data and stream the data back directly from memory. This cuts out the overhead of having to write to the file system.

Not sure I understand -- the CSV (hopefully) doesn't get created until the user triggers the "onclick" event that triggers my exportClick(DataSet) function -- question is how do I get there?

Sorry, I misread your code. It still seems unnecessary to fetch the data before the user clicks 'Export' though. IMHO, it would be better to fetch the data and stream it back to the browser only when the user clicks the button. Otherwise you need to persist your dataset between page requests. This adds complexity to your application and may be inefficient if the user never elects to download the file. If you followed my approach, you wouldn't have the EventHandler problem.
