Of COURSE it is. Because your rentacoder deadline is tonight, right ?
You'd use AJAX to do this, and javascript to insert the new row and to send the data back to the server to save it. There's probably a control in the ASP.NET AJAX library that does it already.

code is
Protected Sub GridView1_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView1.PreRender
Dim GV As GridView = CType(sender, GridView)
Dim intr As Integer = GV.Controls.Count
Dim Tbl As Table = CType(GV.Controls(0), Table)
Tbl.Controls.AddAt(GV.Controls(0).Controls.Count, AddEmptyRow)
'Tbl.Controls.AddAt(GV.Controls(0).Controls.Count, AddEmptyRow)
If a = True Then
Dim i As Integer
For i = 0 To count
Tbl.Controls.AddAt(GV.Controls(0).Controls.Count, AddEmptyRow)
' Tbl.Controls.AddAt(GV.Controls(0).Controls.Count, AddEmptyRow)
Next
End If
End Sub
Function AddEmptyRow() As GridViewRow
Dim GVR As GridViewRow = New GridViewRow(GridView1.Rows.Count, 0, DataControlRowType.EmptyDataRow, DataControlRowState.Insert)
Dim myTableCell As TableCell = New TableCell
For i As Integer = 1 To 3
Dim myHyperLink As TextBox
myHyperLink = New TextBox()
myHyperLink.Width = New Unit(225)
myTableCell.BorderStyle = BorderStyle.Solid
myTableCell.BorderWidth = New Unit(1)
myTableCell.Width = New Unit(700)
myTableCell.BorderColor = Drawing.Color.Black
myTableCell.BackColor = Drawing.Color.MistyRose
myTableCell.Style.Add("text-align", "center")
myTableCell.Controls.Add(myHyperLink)
GVR.Cells.Add(myTableCell)
Next
Return GVR
End Function
Protected Sub b1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles b1.Click
count = count + 1
Dim grsidview As Table = CType(GridView1.FindControl("Tbl"), Table)
GridView1.DataBind()
a = True

Tell them to keep it as asp.net
It will be a monsterous job to convert to PHP

If you want to make it crap, just convert it to VB.NET, no need to go to PHP :P
Seriously, this is a nightmare, tell him to get stuffed. There's no way to do this, apart from starting again and writing it in PHP.
The thing that gets me is that people ask how to do stuff where the obvious thing to ask is why ? I mean, ask the guy why he wants it in PHP, then explain to him why it's a dumb idea. He probably read something on the toilet that convinced him that PHP is cheaper and somehow better for not being microsoft. Which makes him a retard. Your job is to educate him.

To connect to what ? How is this about ASP.NET ? How is this a reasonable question to be asking ? Is it for a class ? Is it for your job ? Do you know any C# at all ?

The browsers render CSS differently, there is no universal way to correct this you will just have to keep testing both browsers.
Is your code small enough to post?
Put up just your main code and css
