sir,
i have a list of users in a gridview.and i want to lock and unlock any user.and for this i have column called status.and this status column contain a linkbutton having default text"lock".means this user is initially unlocked .and now if i want this user to be locked then i will click on lock button and then the "lock" button text will change into "unlock".

What is your question ?
One of my suggestion, rather than use a Lock button for each user, you can put chekbox and Select the User (Checked) and Finally Click the Lock User button outside of Grid. Which will improve your performance and decrease the Database hit.

I use fckeditor in a asp web page like this:
<%
Dim oFCKeditor
Set oFCKeditor = New FCKeditor
oFCKeditor.BasePath = "fckeditor/"
oFCKeditor.Width = "265"
oFCKeditor.Height = "237"
oFCKeditor.Value =""
oFCKeditor.Create "FCKeditor1"
%>
Now,if the text content over oFCKeditor.Height, how can i forbid users to write?
Thanks!

Check your code. You error clearly saying that, The ID which is generated for Texbox is not unique. Means Same Textbox ID generating multiple time.

As i told you in previous post dont use counter2. Instead create a new counter(c1) and increament it in your for loop.
txt.ID = "TextBoxID" + c1.ToString

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)

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...
