コードビハインドのGridviewItemTemplateからasp.NETHiddenFieldにアクセスできません。削除メソッドを実行できるように、これらの非表示フィールドに含まれる値を読み取れるようにする必要があります。コードは次のとおりです
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="MemberList.ascx.cs" Inherits="UserControls_MemberList" %>
<asp:RadioButtonList ID="ReportSelect" runat="server" RepeatDirection="Horizontal">
<asp:ListItem Value="1">All</asp:ListItem>
<asp:ListItem Value="2">Current Members</asp:ListItem>
<asp:ListItem Value="3">Perspective Members</asp:ListItem>
</asp:RadioButtonList>
<asp:Button ID="ReportSelectButton" runat="server" OnClick="ReportSelectButton_Click"
Text="Select Report Type" />
<asp:Button ID="LinkToHomePage" runat="server" Text="Back to Homepage" OnClick="LinkToHomePage_Click">
</asp:Button>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" Height="308px"
Width="1282px" onselectedindexchanged="GridView1_SelectedIndexChanged">
<Columns>
<asp:BoundField HeaderText="First Name" AccessibleHeaderText="FirstName" DataField="FirstName">

<asp:BoundField HeaderText="Last Name" AccessibleHeaderText="LastName" DataField="LastName">

<asp:BoundField HeaderText="Street Address" AccessibleHeaderText="StreetAddress"
DataField="StreetAddress"></asp:BoundField>

<asp:BoundField HeaderText="State" AccessibleHeaderText="State" DataField="State">

<asp:BoundField HeaderText="Zip" AccessibleHeaderText="Zip" DataField="Zip"></asp:BoundField>
<asp:BoundField HeaderText="Birthday" AccessibleHeaderText="Birthday" DataField="Birthday" />
<asp:BoundField HeaderText="Email" AccessibleHeaderText="Email" DataField="Email">

<asp:BoundField HeaderText="PrimaryPhone" AccessibleHeaderText="PrimaryPhone" DataField="PrimaryPhone" />
<asp:BoundField HeaderText="AlternatePhone" AccessibleHeaderText="AlternatePhone"
DataField="AlternatePhone" />
<asp:BoundField HeaderText="Pending" AccessibleHeaderText="Pending" DataField="Pending" />
<asp:BoundField HeaderText="IsMember" AccessibleHeaderText="IsMember" DataField="IsMember" />
<asp:BoundField HeaderText="Username" AccessibleHeaderText="Username" DataField="Username">
</asp:BoundField>
<asp:BoundField HeaderText="Description" AccessibleHeaderText="Descripton" DataField="Description" />
<asp:TemplateField HeaderText="Edit" AccessibleHeaderText="Edit">
<ItemTemplate>
<asp:HyperLink ID="EditUsername" runat="server" NavigateUrl='<%# Link.ToMemberAdmin(Eval("Username").ToString())%>'

<asp:HiddenField ID="HiddenEmail" Value='<%#Bind("Email") %>' runat="server" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
CodeBehind
protected void DeleteButton_Click(object sender, EventArgs e)
{
HiddenField Username = GridView1.FindControl("HidderUsername") as HiddenField;
HiddenField Email = GridView1.FindControl("HiddenEmail") as HiddenField;
string username = Username.Value;
string email = Email.Value;
AdminAccess.DeleteMemberApplication(username, email);
}
どんな助けでも大歓迎です。
