how to apply validation controls on Gridview which is created dynamically

 hi, i created a gridview with two columns and 8 rows dynamically. All the rows are empty and editable at runtime. I am giving column names for this grid from some other .aspx page by passing column names using querystring.Because i am using this grid for three different pairs of column names.  i would like to know how to apply Required Field Validator, Regular Expression Validator  and Range Validator on Gridview textboxes. So that by using those validators i want to validate user inputs. And i would also like to know how to add rows at runtime for this grid. I am using ASP.net 2.0 and C#.net for this.(Visual Studio 2005) The code i am using to create gridview is below. <%@ Page Language="C#" AutoEventWireup="true" CodeFile="LoadData.aspx.cs" Inherits="LoadData" %>  <form id="form1" runat="server">  <div> <asp:GridView ID="GrdDynamic" runat="server" AutoGenerateColumns="False" ForeColor="#333333" BorderColor="GradientInactiveCaption" BorderStyle="Solid" style="z-index: 108; left: 24px; position: absolute; top: 13px">  <FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />  <RowStyle BackColor="#EFF3FB"

Templatefield CheckBox in gridview acting strange

I have an ASP.NET page that contains a gridview. I have to create columns dynamically based on a datatable, some field type info and some header texts. I do that by creating templates. It created the grid fine and all looks good, however when i click a checkbox and the checkedchanged event fires then something odd happens The first time i click its fine and i get the expected values in the event But the second time then the event gets fired with the values from the first time and then again with the values from the checkbox that i actually clicked.. The third time the event gets fired 3 times, first 2 times with the old values and the third with the correct value. And it just keeps going like that Furthermore Let us say i have 10 checkboxes that are checked when i uncheck one the checkedchanged event fires but if i check it again the event doesnt fire and also if i have unchecked 3 checkboxes(and get the extra events) then if i check one of them again i get 2 checked changed events fired for the ones that are still unchecked but no event gets fired for the box that i checked  so now im just baffled   See pastebin link below for code: http://pastebin.com/stcwqsYa
