Question does not make any sense, what do you mean by that ? What about your last post? Did you check my answer ?
What you are cross posting?

I am using the following code to export Data Grid to excel. It works fine, except that it misses the leading '0's in the first column. For example, I have data in first column like '0034566'. When it exports to excel, the data is shown as '34566'. I have tried many things but it's still not working. Please help.
Imports System.Data
Imports System.IO
Partial Class _Default
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
End Sub
Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click
Response.ContentType = "application/vnd.ms-excel"
Response.AddHeader("content-disposition", "attachment;filename=SearchDownload.xls")
Response.Charset = ""
Me.EnableViewState = False
GridView1.AllowPaging = False
Dim dtSupplier As DataTable = DirectCast(ViewState("dtSupplier"), DataTable)
GridView1.DataSource = dtSupplier
GridView1.DataBind()
Dim stringWrite As New System.IO.StringWriter()
Dim htmlWrite As System.Web.UI.HtmlTextWriter = New HtmlTextWriter(stringWrite)
Dim StyleAsText As String = "<style> .StyleAsText{ mso-number-format:\@;} </style>"
GridView1.RenderControl(htmlWrite)
'Response.Write(strStyle)
'Response.Write(stringWrite.ToString())
Response.Write(StyleAsText + stringWrite.ToString())
Response.End()
End Sub
Public Overloads Overrides Sub VerifyRenderingInServerForm(ByVal control As Control)
End Sub
End Class

I think, it because of you are exporting that field as number format.

Ok I have changed my code. I think it should work, But it isn't. Any suggestions? Please check my code below.
Imports System.Data
Imports System.IO
Partial Class _Default
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
End Sub
Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim style As String = "<style> .text { mso-number-format:\@; } </style> "
Response.ClearContent()
Response.AddHeader("content-disposition", "attachment; filename=MyExcelFile.xls")
Response.ContentType = "application/excel"
GridView1.AllowPaging = False
Dim sw As New StringWriter()
Dim htw As New HtmlTextWriter(sw)
GridView1.DataBind()
GridView1.RenderControl(htw)
'Style is added dynamically
Response.Write(style)
Response.Write(sw.ToString())
Response.End()
End Sub
Public Overloads Overrides Sub VerifyRenderingInServerForm(ByVal control As Control)
End Sub
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs)
If e.Row.RowType = DataControlRowType.DataRow Then
e.Row.Cells(0).Attributes.Add("class", "text")
End If
End Sub
End Class

CHeck the below code...
Response.Clear()<br />
Response.Charset = ""<br />
'set the response mime type for excel<br />
Response.ContentType = "application/vnd.ms-excel"<br />
Response.Charset = "iso-8859-1"<br />
'create a string writer<br />
Dim stringWrite As New System.IO.StringWriter<br />
'create an htmltextwriter which uses the stringwriter<br />
Dim htmlWrite As New System.Web.UI.HtmlTextWriter(stringWrite)<br />
dg.DataSource = ds<br />
'bind the datagrid<br />
dg.DataBind()<br />
'tell the datagrid to render itself to our htmltextwriter<br />
dg.RenderControl(htmlWrite)<br />
Dim strStyle As String = "<style>.text { mso-number-format:\@; } </style>"<br />
Response.Write(strStyle + stringWrite.ToString)<br />
Response.AddHeader("Content-Disposition", "attachment")<br />
Response.End()<br />
<br />
<br />
<br />
<br />
Protected Sub dg_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles dg.RowDataBound<br />
If e.Row.RowType = DataControlRowType.DataRow Then<br />
e.Row.Cells(1).Attributes.Add("class", "text")<br />
End If<br />
End Sub<br />
and just change the code in response.write line according to above...

Hi friends
I have a doc file in my project folder. I want the user to download the doc file for their reference. In that case, I used <a> tag
<a href="sample.doc" >download the sample doc</a>
The file opens well in IE in a write mode so that user can edit and save the file in his system memory. When I open the file using firefox, it opens in a read only mode so I m unable to modify/edit the file. I can modify it only after saving the file in my system memory...
I need to open the file in a write mode in firefox browser while open action without saving.
Could u help me how to solve this issue
Advance thanks.

would someone be kind enough to shed me some light on the following concepts? these aren't assignment or exam questions, just things i couldn't find in the book i am reading and unbingable.
* how would forms authentication be made to work if cookies aren't enabled?
* session state can be stored in a cookie or within a munged url. if latter, then for a 'busy' website, there would be a higher likelyhood that a naughty user can replace the session state portion of the url with some random value and 'steal' someone else's session?
* once a user has been authenticated (either via forms or windows), can session state be used from then onwards as a mechanism to identify if a user is who he says he is? at least until the session expires (is made to expire) and then the user has to login again?
* as I understand it, IIS and ASP.Net are both services running in a web server OS. As such they need a logon account to run as. For IIS it is IUSR_[ComputerName] while for ASP.NET (IIS7) it is 'whomever' is entered in the sites application pool. If impersonation is enabled, then it uses the said account to run the .Net codes behind the page. is this correct?
* where do I find it in MMC where to set the account to run IIS under? I couldn't even find the entry for the IIS service in administrative tools, services
muchos gracias

I have a web application developed in Visual Studio 2008 with Crystal Reports 2008. When I run it locally everything works fine. However, on the server I get the following error...

I created the crystalreportviewers12 virtual directory in the IIS and I still get the same error.
Any ideas?

Hi all,
I have a composite ASP.NET server control includes a HTML button that shows a div which allows searching capacities, the Search capacities are implimented using AJAX, im inheriting from WebControl and impliementing INamingContainer and ICallbackEventHandler.
The Control that works fine if you have just one control on the an ASP.NET page.
If you add further controls onto the page the first control still works fully but all contols after that allow the show/hide behaviour but the Ajax bits dont work. There are no errors, the data area just stays blank.
I think i have a problem with the way im registering the callback function. this is the code im using which is in the overridded OnPreRender Method of the Server Control.
string sref = Page.ClientScript.GetCallbackEventReference(this, "arg", "display","", true);
string Callback = "function GetData(arg, context){" + sref + ";}";
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "CallBack", Callback, true);
This outputs the following section of html
<script type="text/javascript">
function GetData(arg, context){WebForm_DoCallback('LookupBox23123',arg,display,"",null,true);}
</script>
As you can see the first parameter of the callback contains the ID of the first control added (I know the ID is abit weird). I Think that is why the first control continues to work with Ajax but the rest don't.
Is there a way i can pass in the control name to the callback method so i can use multiple controls, or can i amend the script Reference to allow this functionality.
Many thanks Phil

Please ignore this now i've worked it out, although if anyone has a better way let me know.
I've used the context to pass the control name through.
string sref = Page.ClientScript.GetCallbackEventReference("context", "arg", "display","context","display_Error", true);
string Callback = "function GetData(arg, context){" + sref + ";}";
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "CallBack", Callback, true);
this means that in my javascript i've got calls like
GetData(Value,"Lookup1");
Cheers Phil
