I want to import the data of a grid view to XL sheet...I used the folllowing code
GridView1.AllowPaging = False
Call btndisplay_Click(sender, e)
Response.Clear()
Response.AddHeader("content-disposition", "attachment;filename=FileName.xls")
Response.Charset = ""
Response.Cache.SetCacheability(HttpCacheability.NoCache)
Response.ContentType = "application/vnd.xls"
Dim stringWrite As New System.IO.StringWriter()
Dim htmlWrite As System.Web.UI.HtmlTextWriter = New HtmlTextWriter(stringWrite)
Me.GridView1.RenderControl(htmlWrite)
Response.Write(stringWrite.ToString())
Response.End()
GridView1.AllowPaging = True
Call btndisplay_Click(sender, e)
The code works but when i have 0 in the begning (like 00ABCD),it dosent take the 0 and tkes ABCD only..
How can i format the column to text (in code behind) so that it would accept zero in the begning

Hai Friends,
I put a label in master page enabled page.I want to get the id of that label in another page where the second page is not a masterpage enabled page.How i get the label control id in the second page.Please help me.

|

You can't, if it doesn't use the master page, then the masterpage does not exist for that page lifecycle. You need to store it in the session or something.

Isn't it obvious ? Don't add a key that is already there. So, check if the key exists and if it does, decide if you want to change the value that's there, or leave it.

If you are using a static variable in a web application, you have to synchronise all access to it. The reason for the error is that two users are adding items at the same time. You are lucky that you got such a descriptive error message, you could just as well have corrupted the HashTable and got some internal error in the HashTable code...
Use a List instead of a HashTable. You are only using the key of the HashTable as an index anyway.
Instead of copying the items one by one into a new collection, just keep them in the collection where they are.
Despite everything, the person most likely to be fooling you next is yourself.

What sort of retard would ask for millions of records and expect it to be responsive ? What sort of UI would you expect to use to show millions of records ?
Fix your SQL so it only returns the data you want to show and make your page size sensible. Then it will work fine.

In sql query is running fine,While fetching less number of records working fine in code,where as taking time to fetch more than one lakh records,
|
|
|
|

I understood that. Like I said, to try to display 100,000 records, is plain retarded. You're not showing that many records in one page, are you ?
