Ok, if you're using the statement you wrote in the post, I believe it is normal that you get an "object not set" error.
You said that you use the following expression:
if (e.Row.RowType == DataControlRowType.DataRow) || (e.Row.RowType == DataControlRowType.Header)
This indicates that if the row is either a data row or a header do something. In case it is a header, there is no data in it and it might throw an error if you attempt to access something that is not there.
I have never used DataItem so I cannot tell you for sure but what I'm sure of is that I use the following and it works very well:
GridViewRow row = e.Row;
if (row.RowType == DataControlRowType.Header)
{
}
if (row.RowType == DataControlRowType.DataRow)
{
}
It could help if you post more code to see exactly what is written.

Yup I agree with you.
The code is as below:
if (e.Row.RowType == DataControlRowType.DataRow )
{
DataRowView rowView = (DataRowView)e.Row.DataItem;
string Code = rowView["CODE"].ToString();
}
Thie fist row doesn't match the condition as row type is DataControlRowType.Header.
But the first row has some data and i want the fist row shouldnt be a DataControlRowType.Header.
Does this helps you to solve the problem

You can choose to remove the header from the GridView if you don't want it at all.
I have tried writing similar lines in my code. I didn't get any error with DataRowView rowView = (DataRowView)e.Row.DataItem. Now I'm thinking that maybe the data binding was not done properly for the GridView? If the data binding was not done, DataItem would be empty and the cast (DataRowView)e.Row.DataItem could thrown an error. I don't see what else could be wrong. Maybe someone can provide a fresh perspective.

Hi guys how to creat note pad in runtime in asp.net plz give some sample code

Your question is illogical. You can't create a notepad in ASP.NET, because you can't save files locally. You can trivially add a text control, and save the contents to the server, however. What do you mean by 'in runtime'. What is it you want to do ?

What do the X's mean ? you probably mean you need to build a regex ? Expresso is a great tool for that.

Use Regular Expression Validator.
\s{3} \s{4}

hi,
This is the regular expression for U.S Phone number(XXX-XXX-XXXX)
((\(\d{3}\) ?)|(\d{3}-))?\d{3}-\d{4}
You can edit it and use it for your work accordingly..

The best you can do is work out in your pages that it has timed out, and redirect to the login page.

Before getting the data from the Session first check is not null.

As Christian told you need to validate session existence on each page_load. It could be something like
if ( session["yoursessionvalue"] == null)
Response.Redirect("Loginpage");
|
|
|
|
|
Check the session value in page load. If it is null then redirect the login page showing the message that your session is time out.

Why is it that suddenly so many questions get the same answer given over and over again ?

Respected Gurus
I have to export a datagrid to excel in asp.net1.1
my code is:---
Private Sub btnExport_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExport.Click
Response.ContentType = "application/vnd.ms-excel"
' Remove the charset from the Content-Type header.
Response.Charset = ""
' Turn off the view state.
Me.EnableViewState = False
'Dim tw As New System.IO.StringWriter
tw = New System.IO.StringWriter
'Dim hw As New System.Web.UI.HtmlTextWriter(tw)
hw = New System.Web.UI.HtmlTextWriter(tw)
' Get the HTML for the control.
DataGrid1.RenderControl(hw)
' Write the HTML back to the browser.
Response.Write(tw.ToString())
' End the response.
Response.End()
End Sub
whenever i run this code i got the error message that control datagrid1_....
must be placed inside a form tag with runat=server.
how to resolve it as all the controls are inside the form tag and runat=server attribute is also there.
Plz suggest.
