Again the same error. What to do?

OnRowCommand="GridView1_RowCommand" runat="server" CellPadding="4" xmlns:asp="#unknown"

The GridView 'view1' fired event PageIndexChanging which wasn't handled.

You can use this javascript function

Place a HTML text box (here its name is Text1)and onBlur event write a function

function abc()
{
var res=document.getElementById("Text1").value;
if(isNaN(res)|| document.getElementById("Text1").value==0)
{
document.form1.Text1.value="";
}
}

Put the validation expression as

validationexpression=\d{0,10}

its only accepting only integer values in the range 0 to 10

or Change it to

ValidationExpression="[0-9]*"

<asp:regularexpressionvalidator id="RegularExpressionValidator1" runat="server" controltovalidate="TextBox1" errormessage="Please Enter only Numeric" validationexpression="[0-9]*" xmlns:asp="#unknown">

You could use a comparevalidator to check the value is greater than 0

You can use regex to find if the entered data is a "Natural Number". Google will help you find it.

Also, make sure that the regex should NOT have a check that text begins with 0. Reason being user can enter 0000003434 which is a valid entry as per your criteria.

value of a cell of selected row

Hi.
For a GridView, how to retrieve the cell values of a selected row?
Thank you!

You asked this question before and I gave you the answer.
The reason why it could not have worked for you is most likely your setting a row's state as Selected wrong.
My question therefore: how do you select the row, in other words, what code do you exectue in the application, so that it recognizes your desired row as .SelectedRow.
Looking at it very hard or highlighting is not the right way.

Usually, where you actually do Select a row, getting data from it is really, really easy.

string something = Gridview1.SelectedRow.Cells[0].Text;

Honestly, do post some more information, maybe some code of your own if you want people's replies to be relevant.

var question = (_2b || !(_2b));

Thank you Greg Chelstowski;
I tried your code and there:

protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
    {
        GridViewRow row = GridView1.Rows[GridView1.SelectedIndex];
        string strValCell = row.Cells[2].Text;
    }

//and 

public void GridView1_SelectedIndexChanged(Object sender, EventArgs e)
    {
      
        TextBox1.Text = GridView1.SelectedRow.Cells[2].Text; 
    }

but it doesn't work

" any result"

and if i do

public void GridView2_SelectedIndexChanged(Object sender, EventArgs e)
    {
                TextBox tb = GridView1.SelectedRow.FindControl("id0") as TextBox;
        if (tb != null)

         TextBox1.Text = tb.Text;

        else
           TextBox1.Text = "no data";
       
    }

I have always "no data"

<columns>

make the gridview paging property true and write fire the event of grid view paging.
or follow the code.

eg.
{
protected void grdemp_PageIndexChanging(object sender, GridViewPageEventArgs e)
//grdemp is ame of grid view
{
grdemp.PageIndex = e.NewPageIndex;
}
}

I am looking for code where i can integrate the outlook with asp.net
I want to create an appoint from asp.net in outlook
here is the code for that
Imports System.Reflection
Imports Outlook = Microsoft.Office.Interop.Outlook

Module Module1

Sub Main()
' Create an Outlook application.
Dim oApp As Outlook.Application = New Outlook.Application()

' Create a new AppointmentItem.
Dim oAppt As Outlook.AppointmentItem = oApp.CreateItem(Outlook.OlItemType.olAppointmentItem)

' Set some common properties.
oAppt.Subject = "Created using OOM in VB .NET"
oAppt.Body = "Hello World"
oAppt.Location = "Room 1201"

oAppt.Start = Convert.ToDateTime("05/31/2004 9:00:00 AM")
oAppt.End = Convert.ToDateTime("05/31/2004 1:00:00 PM")
oAppt.ReminderSet = True
oAppt.ReminderMinutesBeforeStart = 5
oAppt.BusyStatus = Outlook.OlBusyStatus.olBusy
oAppt.IsOnlineMeeting = False

' Save to Calendar.
oAppt.Save()

' Clean up.
oApp = Nothing
oAppt = Nothing

You're an idiot. I explained this to you already. This is VB code, it will create an appointment on the SERVER. You cannot create or delete appointments on the client machine. Buy a book on ASP.NET and read it, you obviously have no idea how it works.

You need to Url encode that ReturnUrl querystring otherwise the ampersands get treated as other variables for login.aspx
