推荐答案

以下代码片段将隐藏与gridview列关联的值.

The following code snippet will to hide the value associated with gridview column.

<asp:GridView ID="gvData" runat="server"

                            AutoGenerateColumns="False" EmptyDataText="There are no data records to display."

                            CellPadding="4" ForeColor="#333333" GridLines="None" Width="100%" Height="272px" Style="font-family: Consolas">
                            <RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
                            <Columns>
                                <asp:TemplateField HeaderText="Data 1">
                                    <ItemTemplate>
                                        <asp:Label ID="lblId" runat="server" Text='<%# Bind("id") %>' Visible="false"></asp:Label>
                                        <asp:Label ID="lblData1" runat="server" Text='<%# Bind("data1") %>'></asp:Label>
                                    </ItemTemplate>
                                </asp:TemplateField>
                                <asp:TemplateField HeaderText="Data 2">
                                    <ItemTemplate>
                                        <asp:Label ID="lblData2" runat="server" Text='<%# Bind("data2") %>'></asp:Label>
                                    </ItemTemplate>
                                </asp:TemplateField>
                            </Columns>
                        </asp:GridView>

id列与不可见的标签关联.因此，您可以访问与此标签绑定的数据.

The id column is associated with non visible label. So you can access the data that is binded with this label.

使用此代码

Use this code

<asp:GridView ID="GridView1" runat="server" CssClass="GridViewStyle"

        DataKeyNames="id" AutoGenerateColumns="False" OnRowDeleting="DeleteRecord"

               AllowPaging="True" AllowSorting="true" PageSize="15"

          OnPageIndexChanging="ChangePage" OnSorting="SortRecords">
            
           <Columns>
           <asp:BoundField DataField="id" HeaderText="S No" ReadOnly="True"  SortExpression="id" Visible="false" />

只需将其宽度设置为0％.

希望对您有所帮助.

Just give its width to 0%.

Hope this can help you.
