You Can export the value in excel Sheet:
You are required to keep textboxes and Combo boxes value in any container like dataset or array List .....and assign these source to GridView.
For example:
string s = "select * from person";
DataSet ds = GetDataSet(s);
GridView1.DataSource = ds;
GridView1.DataBind();
Response.ContentType = "application/ms-excel";
Response.AddHeader("Content-Disposition", "inline;filename=ExcelRPT.xls");
Good Luck !

the following are problems/doubts in asp.net
1)in web.config i given session timeout=20
then after 20 min. session will expired
is it correct
if so, how can we know programatically the session is expired
depending this i will redirect the user to a new page
2)i m doing on line booking site for a client
he given a image which contains 900 boxes with numbering
if the user books 1 box then the box with corresponding number 1 will turn into red color
my client wants to place "buttons" at the respective boxes at designing time and at run time it should turn into red
now my main doubt is...
if we place 900 buttons does the page performance will be reduced...

For your first question,
You need to have a Session variable when the Session is started like Session("IsUserLoggedIn") and set a value. When the Session expired, Session("IsUserLoggedIn") will be Nothing. Now you can say the session expired.

The performance depends on the what the button do when they are click (both on client and server-side). Placing that much controls will look odd. May be you can try with tables and tds.

Are you using "Global.asax" file to handle the Session_End event?
I did the following in my appplication and its working fine for me.
In web.config,
<sessionstate timeout="1" />
In Login Page's button click,
<code>Session("LoggedIn") = True
Response.Redirect("Default.aspx")</code>
In the Default Page's Page Load event,
If Not Session("LoggedIn") Then
Response.Write("Session Expired")
Else
Response.Write("Session is active.")
End If
I am not using any Global.asax file.
Hope this would help you. If you still face the problem, email me the sample. I will look into it.

In the datalist , i have a label control in the datalist , at runtime , it gets bind with the database table . The label width is fixed and the height changes itself , as per its text , Now the problem is when i view the website in the internet explorer , it works fine , but when i view the site in opera or in the Mizilla Firefox , its second record gets overwrite with the first record , reason is , the text of first record is more the the first one.The datalist is iterating the records in the vertical direction.
How should i overcome this problem ?

Check the Height Property. If the content of the control is bigger then the Height of that control then Internet Explorer will adjust the Height accordingly. but the FireFox and Opera are more Standard base Browser, so they will stricktly follows the CSS Specification, and they will not increase the Height of the control, even if the content overlaps. so either you just leave the Height Property Blank or Increase it so that the content will not overlap.

Hi all,
If i have a number formatted like this 15,000 using a regex or so and i need to read it in javascript using parsefloat iam getting the result of 15
maybe because it is considering the "," as decimal point. is there a way i can read 15,000 as integer or decimal of 15000 so i can get the exact results in my javascript.
thanks

If your controls are in Content Place Holder / Panel / Place Holder / Update Panel. Then you cannot directly access them. you have to use the FindControl Method[^]
Make sure that you are following the correct sequence.
i.e.
x = Page.FindControl("your update panel")
y = x.FindControl("your control in update panel");
or you can stack trace and use the direct pre defined name
i.e. ctl001ContentPlaceHolder.<your control>
Hope this will help...

hello,
I'm working on a web site using asp.net. I have to display dynamic froms .
the form will be discribed in an xml file , after that element of form described in the xml file will be converted to objects by XML serialisation and displayed with fonction controls.add(element). my pb that I don't know all possibilities offred by asp.net to fixe its layout.
what proprities can I add to my objects to fix its layout? and if it's possible how can I use it proprities?
at the moment I use a table to do that and colspan and leftcal . so I ask if there is other methode.
rq: I use vb not c#.
thanks for your help.

That is depended on how much flexibility you want. if you want complete dynamic layout, then whatever you are doing is fine. if the overall layout is fixed and just the controls are different, then you can statically add a table and put the PlaceHolders in each cell of the table, and then you can assign PlaceHolder1.Controls.Add() to fill out the layout.

thanks for your answer ,but I want that all be dynamic in my work. I dont want to fixe staticly a table. so can I do that differenty.
if there is a way, plz tell me how and what attributes shall I add to my objects to fixe its layout?
colum span et left col are suffisent?
In conclusion I want an idea that make a dynamic form (and I will not use a static object) from a description (vb class form ens<element> element can be label or radio button or text.....) I will loop if there is an element, so I want a solution that resolve pb of layout, I what to know what attributes to add to my element class and why (how to use it).
I know that my english is not good , so I wish I explain correctly the pb .
thanks for your answer.
