Hi,

I have created a Custom Control with textbox.

I am calling it in GridView. When an Update event is fired it always saves 0.
I have used following code , could any one help in the same.

Following is the code used for custom control.

ASCX Code
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="ItemRequiredTextBox.ascx.cs"
Inherits="ItemRequiredTextBox" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %>

<asp:TextBox ID="txtWin_Delievered_Qty" runat="server" >

<asp:FilteredTextBoxExtender ID="ftbe3" runat="server" TargetControlID="txtWin_Delievered_Qty"
ValidChars="1234567890" />
<asp:CompareValidator ID="CompareValidator1" runat="server" Display="None" ValueToCompare='<%# this.Text2 %>' ControlToValidate="txtWin_Delievered_Qty" Type="Integer"
ErrorMessage="Quantity to be delievered can not be More than Required Quantity"
Operator="LessThanEqual">

<asp:ValidatorCalloutExtender ID="ValidatorCalloutExtender1" TargetControlID="CompareValidator1"
runat="server">

<asp:CompareValidator ID="CompareValidator2" runat="server" Display="None" ValueToCompare='<%# this.Text1 %>' ControlToValidate="txtWin_Delievered_Qty" Type="Integer"
ErrorMessage="Quantity delievered can not be less than delievered Quantity" Operator="GreaterThanEqual">
