Asp.net 不想在网格中显示数据的Id

我试图在网格上显示表数据，但我不想显示表Id

        <asp:BoundField DataField="Expense_Category" HeaderText="Expense Category" 
            SortExpression="Expense_Category" ApplyFormatInEditMode="True" 
             />
        <asp:BoundField DataField="Expense_Description" 
            HeaderText="Expense Description" SortExpression="Expense_Description" 
            ApplyFormatInEditMode="True" />
        <asp:BoundField DataField="Expense_Date" HeaderText="Expense Date" 
            SortExpression="Expense_Date" ApplyFormatInEditMode="True" 
            DataFormatString="{0:d}" HtmlEncode="False" />
        <asp:BoundField DataField="Amount" HeaderText="Amount" 
            SortExpression="Amount" ApplyFormatInEditMode="True" 
             />
    </Columns>
</asp:GridView>
</div>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
    ConnectionString="<%$ ConnectionStrings:testAzharConnectionString %>" 
    SelectCommand="SELECT Expense_Category, Expense_Description, Amount, Expense_Date FROM [CompanyExpenses3]"
    UpdateCommand="Update [CompanyExpenses3] SET Expense_Category=@Expense_Category, Expense_Description=@Expense_Description,Expense_Date=@Expense_Date, Amount=@Amount WHERE ExpenseId=@ExpenseId"
          OnUpdated="OnDSUpdatedHandler"></asp:SqlDataSource>
</asp:Content>

我还保留了ApplyFormatInEditMode=True

        <asp:BoundField DataField="Expense_Category" HeaderText="Expense Category" 
            SortExpression="Expense_Category" ApplyFormatInEditMode="True" 
             />
        <asp:BoundField DataField="Expense_Description" 
            HeaderText="Expense Description" SortExpression="Expense_Description" 
            ApplyFormatInEditMode="True" />
        <asp:BoundField DataField="Expense_Date" HeaderText="Expense Date" 
            SortExpression="Expense_Date" ApplyFormatInEditMode="True" 
            DataFormatString="{0:d}" HtmlEncode="False" />
        <asp:BoundField DataField="Amount" HeaderText="Amount" 
            SortExpression="Amount" ApplyFormatInEditMode="True" 
             />
    </Columns>
</asp:GridView>
</div>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
    ConnectionString="<%$ ConnectionStrings:testAzharConnectionString %>" 
    SelectCommand="SELECT Expense_Category, Expense_Description, Amount, Expense_Date FROM [CompanyExpenses3]"
    UpdateCommand="Update [CompanyExpenses3] SET Expense_Category=@Expense_Category, Expense_Description=@Expense_Description,Expense_Date=@Expense_Date, Amount=@Amount WHERE ExpenseId=@ExpenseId"
          OnUpdated="OnDSUpdatedHandler"></asp:SqlDataSource>
</asp:Content>

如果我执行此操作，则datafield visible=false。它不适用于“编辑”命令

        <asp:BoundField DataField="Expense_Category" HeaderText="Expense Category" 
            SortExpression="Expense_Category" ApplyFormatInEditMode="True" 
             />
        <asp:BoundField DataField="Expense_Description" 
            HeaderText="Expense Description" SortExpression="Expense_Description" 
            ApplyFormatInEditMode="True" />
        <asp:BoundField DataField="Expense_Date" HeaderText="Expense Date" 
            SortExpression="Expense_Date" ApplyFormatInEditMode="True" 
            DataFormatString="{0:d}" HtmlEncode="False" />
        <asp:BoundField DataField="Amount" HeaderText="Amount" 
            SortExpression="Amount" ApplyFormatInEditMode="True" 
             />
    </Columns>
</asp:GridView>
</div>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
    ConnectionString="<%$ ConnectionStrings:testAzharConnectionString %>" 
    SelectCommand="SELECT Expense_Category, Expense_Description, Amount, Expense_Date FROM [CompanyExpenses3]"
    UpdateCommand="Update [CompanyExpenses3] SET Expense_Category=@Expense_Category, Expense_Description=@Expense_Description,Expense_Date=@Expense_Date, Amount=@Amount WHERE ExpenseId=@ExpenseId"
          OnUpdated="OnDSUpdatedHandler"></asp:SqlDataSource>
</asp:Content>

如何从网格中隐藏Id

        <asp:BoundField DataField="Expense_Category" HeaderText="Expense Category" 
            SortExpression="Expense_Category" ApplyFormatInEditMode="True" 
             />
        <asp:BoundField DataField="Expense_Description" 
            HeaderText="Expense Description" SortExpression="Expense_Description" 
            ApplyFormatInEditMode="True" />
        <asp:BoundField DataField="Expense_Date" HeaderText="Expense Date" 
            SortExpression="Expense_Date" ApplyFormatInEditMode="True" 
            DataFormatString="{0:d}" HtmlEncode="False" />
        <asp:BoundField DataField="Amount" HeaderText="Amount" 
            SortExpression="Amount" ApplyFormatInEditMode="True" 
             />
    </Columns>
</asp:GridView>
</div>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
    ConnectionString="<%$ ConnectionStrings:testAzharConnectionString %>" 
    SelectCommand="SELECT Expense_Category, Expense_Description, Amount, Expense_Date FROM [CompanyExpenses3]"
    UpdateCommand="Update [CompanyExpenses3] SET Expense_Category=@Expense_Category, Expense_Description=@Expense_Description,Expense_Date=@Expense_Date, Amount=@Amount WHERE ExpenseId=@ExpenseId"
          OnUpdated="OnDSUpdatedHandler"></asp:SqlDataSource>
</asp:Content>

这是我的密码

<%@ Page Title="" Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="EditExpenses.aspx.cs" Inherits="EditExpenses" %>

        <asp:BoundField DataField="Expense_Category" HeaderText="Expense Category" 
            SortExpression="Expense_Category" ApplyFormatInEditMode="True" 
             />
        <asp:BoundField DataField="Expense_Description" 
            HeaderText="Expense Description" SortExpression="Expense_Description" 
            ApplyFormatInEditMode="True" />
        <asp:BoundField DataField="Expense_Date" HeaderText="Expense Date" 
            SortExpression="Expense_Date" ApplyFormatInEditMode="True" 
            DataFormatString="{0:d}" HtmlEncode="False" />
        <asp:BoundField DataField="Amount" HeaderText="Amount" 
            SortExpression="Amount" ApplyFormatInEditMode="True" 
             />
    </Columns>
</asp:GridView>
</div>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
    ConnectionString="<%$ ConnectionStrings:testAzharConnectionString %>" 
    SelectCommand="SELECT Expense_Category, Expense_Description, Amount, Expense_Date FROM [CompanyExpenses3]"
    UpdateCommand="Update [CompanyExpenses3] SET Expense_Category=@Expense_Category, Expense_Description=@Expense_Description,Expense_Date=@Expense_Date, Amount=@Amount WHERE ExpenseId=@ExpenseId"
          OnUpdated="OnDSUpdatedHandler"></asp:SqlDataSource>
</asp:Content>

编辑费用

        <asp:BoundField DataField="Expense_Category" HeaderText="Expense Category" 
            SortExpression="Expense_Category" ApplyFormatInEditMode="True" 
             />
        <asp:BoundField DataField="Expense_Description" 
            HeaderText="Expense Description" SortExpression="Expense_Description" 
            ApplyFormatInEditMode="True" />
        <asp:BoundField DataField="Expense_Date" HeaderText="Expense Date" 
            SortExpression="Expense_Date" ApplyFormatInEditMode="True" 
            DataFormatString="{0:d}" HtmlEncode="False" />
        <asp:BoundField DataField="Amount" HeaderText="Amount" 
            SortExpression="Amount" ApplyFormatInEditMode="True" 
             />
    </Columns>
</asp:GridView>
</div>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
    ConnectionString="<%$ ConnectionStrings:testAzharConnectionString %>" 
    SelectCommand="SELECT Expense_Category, Expense_Description, Amount, Expense_Date FROM [CompanyExpenses3]"
    UpdateCommand="Update [CompanyExpenses3] SET Expense_Category=@Expense_Category, Expense_Description=@Expense_Description,Expense_Date=@Expense_Date, Amount=@Amount WHERE ExpenseId=@ExpenseId"
          OnUpdated="OnDSUpdatedHandler"></asp:SqlDataSource>

你可以写一个css类

        <asp:BoundField DataField="Expense_Category" HeaderText="Expense Category" 
            SortExpression="Expense_Category" ApplyFormatInEditMode="True" 
             />
        <asp:BoundField DataField="Expense_Description" 
            HeaderText="Expense Description" SortExpression="Expense_Description" 
            ApplyFormatInEditMode="True" />
        <asp:BoundField DataField="Expense_Date" HeaderText="Expense Date" 
            SortExpression="Expense_Date" ApplyFormatInEditMode="True" 
            DataFormatString="{0:d}" HtmlEncode="False" />
        <asp:BoundField DataField="Amount" HeaderText="Amount" 
            SortExpression="Amount" ApplyFormatInEditMode="True" 
             />
    </Columns>
</asp:GridView>
</div>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
    ConnectionString="<%$ ConnectionStrings:testAzharConnectionString %>" 
    SelectCommand="SELECT Expense_Category, Expense_Description, Amount, Expense_Date FROM [CompanyExpenses3]"
    UpdateCommand="Update [CompanyExpenses3] SET Expense_Category=@Expense_Category, Expense_Description=@Expense_Description,Expense_Date=@Expense_Date, Amount=@Amount WHERE ExpenseId=@ExpenseId"
          OnUpdated="OnDSUpdatedHandler"></asp:SqlDataSource>
</asp:Content>

<style type="text/css">
.hiddencol
    {
        display:none;
    }
    </style>

这里0是您必须隐藏的列的索引。

否，您可以编写一个CSS类作为hiddencol，并将其应用于要隐藏Gridview的onrowcreated事件的特定列。。它正在工作@毫无疑问。。再次非常感谢。

        <asp:BoundField DataField="Expense_Category" HeaderText="Expense Category" 
            SortExpression="Expense_Category" ApplyFormatInEditMode="True" 
             />
        <asp:BoundField DataField="Expense_Description" 
            HeaderText="Expense Description" SortExpression="Expense_Description" 
            ApplyFormatInEditMode="True" />
        <asp:BoundField DataField="Expense_Date" HeaderText="Expense Date" 
            SortExpression="Expense_Date" ApplyFormatInEditMode="True" 
            DataFormatString="{0:d}" HtmlEncode="False" />
        <asp:BoundField DataField="Amount" HeaderText="Amount" 
            SortExpression="Amount" ApplyFormatInEditMode="True" 
             />
    </Columns>
</asp:GridView>
</div>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
    ConnectionString="<%$ ConnectionStrings:testAzharConnectionString %>"
