Dealing with popup windows can be tricky and not safe (popup blockers
may negate your efforts.)

The easiest way would be to employ the "confirm" statement in
client-side javascript.

For example, consider the most common case - adding a confirmation
dialog when user attempts to delete a record from a datagrid (gridList
below) on ASP.NET page. The server-side event handler will only
execute if the user clicks "yes" on the client-side, causing the event
to fire:

In your HTML:

<asp:TemplateColumn>
<ItemTemplate>
<asp:LinkButton id="linkDelete" runat="server"
CommandName="Delete">Delete</asp:LinkButton>
</ItemTemplate>
</asp:TemplateColumn>


In your code behind:

// The below will add a confirmation dialog
// to each linkDelete instance at runtime
private void gridList_ItemDataBound(object sender,
DataGridItemEventArgs e )
{
if( e.Item.FindControl("linkDelete") !+ null )
{
LinkButton deleteButton =
e.Item.FindControl("linkDelete") as LinkButton;

deleteButton.Attributes.Add( "onclick",
@"javascript:return confirm('Are you sure you want to delete this
record?');" )

}
}

private void gridList_DeleteCommand( object source,
DataGridCommandEventArgs e )
{
// Delete the record here
}

this is in asp.net and language is vb
Public Shared Sub Alert(ByRef aspxPage As System.Web.UI.Page, ByVal
strMessage As String)
Dim strScript As String = "<script language=JavaScript>alert('" &
strMessage & "')</script>"
If (Not aspxPage.IsStartupScriptRegistered("strKey1")) Then
aspxPage.RegisterStartupScript("strKey1", strScript)
End If
End Sub

the above function is a public shared function which accepts page in which
alert is required and second param is of the message which you want to
dispaly.....
if u write this function in a class then call the class.function name with
params that should work.

For example if i wirte above code in "uitl .class"
then while calling i have to from webform as util.Alert(me, "Hello World")

for confirm box

Public Shared Sub Confirm(ByRef btn As WebControls.Button, ByVal strMessage
As String)
btn.Attributes.Add("onclick", "return confirm('" & strMessage & "');")
End Sub

write this code in a static class called util
in webform load you have to map the particular event to this confirm box
with the following systax
Me.button.Attributes.Add("onclick", "return confirm('Your message goes
here');")

this above code should work, further quires feel free to contact
