C# 如何从gridview中的相应按钮单击中获取特定行值

我声明了一个gridview，其中一些字段是从数据库绑定的。我添加了一个项目模板，其中有一个文本框和按钮。现在，当我单击按钮时，我想捕捉一列的值和对应行的文本框。我怎样才能完成它

我的aspx gridview标记：

<asp:GridView ID="GridView2" runat="server" AutoGenerateColumns="False" DataKeyNames="FOODITEM_ID" DataSourceID="SqlDataSource2" EnableModelValidation="True" OnSelectedIndexChanged="GridView2_SelectedIndexChanged"
    OnRowCommand="GridView2_OnRowCommand">
    <Columns>
        <asp:BoundField DataField="FOOD_ITEM_NAME" HeaderText="FOOD_ITEM_NAME" SortExpression="FOOD_ITEM_NAME" />
        <asp:BoundField DataField="FOODITEM_ID" HeaderText="FOODITEM_ID" ReadOnly="True" SortExpression="FOODITEM_ID" />
        <asp:BoundField DataField="PRICE" HeaderText="PRICE" SortExpression="PRICE" />
        <asp:BoundField DataField="DAY_AVAILABLE" HeaderText="DAY_AVAILABLE" SortExpression="DAY_AVAILABLE" />
        <asp:BoundField DataField="TIME_AVAILABLE" HeaderText="TIME_AVAILABLE" SortExpression="TIME_AVAILABLE" />
        <asp:BoundField DataField="DISCOUNT_PERCENTAGE" HeaderText="DISCOUNT_PERCENTAGE" SortExpression="DISCOUNT_PERCENTAGE" />
        <asp:BoundField DataField="START_DATE" HeaderText="START_DATE" SortExpression="START_DATE" />
        <asp:BoundField DataField="DEADLINE" HeaderText="DEADLINE" SortExpression="DEADLINE" />
        <asp:BoundField DataField="Rating" HeaderText="Rating" SortExpression="Rating" />
        <asp:TemplateField ShowHeader="False">
            <ItemTemplate>
                 <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
                 <asp:Button ID="Button1" runat="server" CausesValidation="false" CommandName="Add"
                    Text="Add" CommandArgument='<%# ((GridViewRow) Container).RowIndex  %>' />
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

现在，当我按下按钮时，如何获取相应行的文本框和其他字段的值。

Flowwing代码应该可以工作：

void GridView2_OnRowCommand(Object sender, GridViewCommandEventArgs e)
 {
    if(e.CommandName=="Add")
    {
      int index = Convert.ToInt32(e.CommandArgument);
      GridViewRow selectedRow = CustomersGridView.Rows[index];
      string otherFieldText = row.Cells[0].Text; // put othe fields' index
      TextBox txt = (TextBox)row.FindControl("TextBox1"); // Textbox
      string txtVal = txt.text; // Textbox value
    }
}

你遗漏了一些东西，所以我决定给你我的完整样品

第一个aspx代码。请注意，我使用命令名（编辑、删除、取消、更新）来执行相应的命令

其次，我绑定了“ItemsGridView\u RowUpdate”以捕获新值（这就是您要寻找的）

快乐编码
