I have a user control embedded in a gridview as an EditItemTemplate.
When updating, the value is not saved to the database. I have an
SQLDataSource attached to the Gridview. Can someone point me to a good
example or discussion about the two way databinding. I use C#. thanks
My source is as follows:
User Control
<%@ Control Language="C#" AutoEventWireup="true"
CodeFile="uc_Gridview_Percentage_Textbox.ascx.cs"
Inherits="uc_Gridview_Percentage_Textbox" %>
<asp:TextBox ID="gvtxtPCT" runat="server" Text='<%# Bind("modifier")
%>' CausesValidation="True" CssClass="gridview_edit_percentage"
MaxLength="7"></asp:TextBox>
<asp:RequiredFieldValidator ID="gvrfvPCT" runat="server"
ControlToValidate="gvtxtPCT"
ErrorMessage="Percentage is Required" >*</asp:RequiredFieldValidator>
<asp:RangeValidator ID="gvrgvPCT" runat="server"
ControlToValidate="gvtxtPCT" ErrorMessage="Percentage must be between
-100.00 and 100.00" MaximumValue="100.00" MinimumValue="-100.00"
SetFocusOnError="True" Type="Currency">*</asp:RangeValidator>
