        If e.Row.RowType = DataControlRowType.DataRow Then
            Dim id As Integer
            id = GridView1.Rows.Count
            If id = 1 Then
                Exit Sub
            End If
            Dim btn As Button = e.Row.FindControl("button1")

Hi,
Do you want to delete record from DB after pressing the delete button.? If yes then you can try the following.
1 ) Add appropriate buttons in your aspx page.

<asp:TemplateField>
<ItemTemplate>
	<asp:Button ID="btnDelete" Text="Delete" CommandArgument=''<%#DataBinder.Eval(container,"dataitem.ID")%>'' CommandName="DELETECURRENTROW" OnClientClick="return confirm('Are you sure you want to delete this record?')" runat="server" />
</ItemTemplate> 
							                </asp:TemplateField>

2) Inside your .vb file you should now handle the proper action in following way.

Protected Sub gvTest_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles gvTest.RowCommand
            Dim ID As Integer = CInt(e.CommandArgument)
            Select Case e.CommandName
                Case "DELETECURRENTROW"
'Execute your Sql for Delete operation. The Record is deleted based on ID generated above.
                    ScriptManager.RegisterStartupScript(Me.Page, Me.GetType(), "STATUS_MESSAGE", "alert('Record deleted for ID:" & ID & "');", True)
                    'Function BindYourGridView()
            End Select
        End Sub

tahnk for repaly when i run the page and click on delete button i got this error

Invalid postback or callback argument.  Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page.  For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them.  If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

Well, There is a script running in the above code. Either set enableEventValidation=false in your aspx page header or remove the script from file.

Also mark this thread as solved when you have your answer. :)
