Hi,
public static void ExportDataSetToExcel(DataSet ds, string filename)
{
HttpResponse response = HttpContext.Current.Response;
// first let's clean up the response.object
response.Clear();
response.Charset = "";
// set the response mime type for excel
response.ContentType = "application/vnd.ms-excel";
response.AddHeader("Content-Disposition", "attachment;filename=\"" + filename + "\"");
// create a string writer
using (StringWriter sw = new StringWriter())
{
using (HtmlTextWriter htw = new HtmlTextWriter(sw))
{
// instantiate a datagrid
DataGrid dg = new DataGrid();
dg.DataSource = ds.Tables[0];
dg.DataBind(); dg.RenderControl(htw);
response.Write(sw.ToString());
response.End();
}
}
}
This is the code which i am using to export data in excel format.But in excel it wont allow '0'(zero) number .ie for zipcode it wont allow to save 0978678 coz zero is starting element
but it will allow 890453 or 506889 like that. i just want one field (here zipcode field) as text field. Is there any way to do that?

I turned off Dynamic ports in VS2008 for a project because I need to configure an external app with a url to my application so the port needs to be the same every time.
The problem is now VS returns an error "Unable to launch the ASP.NET Development Server. Port 'n' is in use."
How can I get my system to release this port so it can be reserved and used only by my website?

Yes.
What problem are you getting ?
Below is my web.config entry.
<appSettings>
<add key="k" value="123"/>
</appSettings>
Here is my Session_End Code.
void Session_End(object sender, EventArgs e)
{
string myval = ConfigurationManager.AppSettings["k"].ToString();
}
On Session_End, I am getting value myval=123.

Session end has nothing to deal with ConfigurationManager.
ConfigurationManageris a static class that Reads different section of ASP.NET config file and gives you the data.
I think it should be accessible from anywhere, even from Application_end. 
There might be some other issue with it, it is nothing to deal ConfigurationManager.

Hi.
I am fairly new to asp.net, and have a problem with a page I am working on. The page contains some textboxes, and a button. When the button is clicked, the codebehind fetches the textbox contents. If the user did something wrong, he is redirected to the same page again, but before that the textbox contents is saved in the session. When the page loads again the textboxes are now filled with this sessiondata so the user doesent have to input all the data from scratch again. But when the button is clicked the second time, the textbox content I read is the old content, and not the new data the user has typed in. How come?
To make my problem a bit easier to understand:
1. Page loads
2. User types "John" in the name textbox, and fills out other textboxes
3. User clicks the submit button
4. Codebehind reads "john" from the name textbox
5. Codebehind registers an error from the other stuff the user has filled in, and redirects to the same page with all textbox contents saved in session
6. Page loads, and all textboxes are filled from the session data
7. User changes the text in the name textbox to "Joe"
8. User clicks submit
9. Codebehind reads "john" from the name textbox - How come?!
Really hope you can help me understand this!
Thanks alot

It should not happen.Might be the case when user changes the data in the textbox and click submit then on pageload you are again filling the data from session.Debug the code and check the values in immediate window you might the get the issue.
One more thing, why you are taking the help of session, you can use viewstate.Enable the viewstate of the contrls on the page that will suffice your requirement.

Relation of textbox and ViewState is something different with respect to other controls. If you make EnableViewState=False; for Textbox, still it will maintain the postback data. Why ?
First of all you need to know what actually happened during ASP.NET Page life cycle and ViewState.
In the ASP.Net page life cycle, two events related with View State.
1. Load View State : Where view state data is loading for the control and which happened before Page_Load.
2. Save View State : Where control data store in a hidden field before the Page_Render.
Now, If you disable the ViewState for the control it should store the view state data but, you are saying in Textbox, after you disabled the view state , control holds the data after postback,
Here is the Trick, There is another event fired during Page Life Cycle, which is, Load PostBack Data
ASP.NET controls which implement IPostBackEventHandler will load its value from the appropriate postback data. This value is not read from view state but from Postback From and this is true for those control which implements the IPostBackEventHandler and TextBox is one such control.
Hope you got my point.

You are right Abhijit. But Load PostBack Data is called only for input controls those implement IPostBackEventHandler . For rest of the controls, viewstate could be used.
Thanks for adding it in detail.

Thanks alot for all your answers.
I´ve tried with the viewstate, but It didnt really work. It prolly would have if I tried for a longer time 
Instead I found out that the page load method is called several times, even if the page isnt loaded. So in that way the old values were set.
But how come the page_load method is called often, even if the user hasnt done anything on the page?
Thanks again

Hi All,
I am converting HTML to PDF using itextsharp.dll. My HTML conatins table and
many rows. When a row goes to next page, its cells data is not shown in pdf
document. Initially, I fixed it by changing top and bottom margins. But it
caused problem in other cases. Note that I am getting HTML from user
control. When I copy this HTML in htm file, It shows all the data correctly.
But in pdf it does not show.
Any help?
Thanks,

SELECT SUM(Amount)
FROM AllTransactions
WHERE (TransCode <> 0)
AND BranchKey = 'branchkey'
You should also look at parameterizing your query.
