在gridview的页脚创建一个新行

本文关键字：一个 新行 创建 gridview | 更新日期: 2023-09-27 18:11:55

我有一个网格视图里面有一些列然后是FooterStyle

我想在页脚下面添加一行。

这是我的GridView:

<asp:GridView ID="cartGrid" runat="server" AutoGenerateColumns="false" 
    ShowFooter="true" CssClass="cartTbl" onrowdatabound="cartGrid_RowDataBound" OnRowEditing="cartGrid_RowEditing" OnRowCancelingEdit="cartGrid_RowCancelingEdit"
    onrowupdating="cartGrid_RowUpdating" EmptyDataText="There are no items in your cart.">
    <Columns>
        <asp:BoundField DataField="ItemNo" HeaderText="Item No." ReadOnly="true" />
        <asp:BoundField DataField="ItemDesc" HeaderText="Item Description" ReadOnly="true" />
        <asp:BoundField DataField="Price" HeaderText="Price" DataFormatString="{0:C}" ReadOnly="true" />
        <asp:TemplateField HeaderText="Quantity">
            <ItemTemplate>
                <asp:Label ID="qLbl" runat="server" Text='<%# Bind("numItems") %>' />
            </ItemTemplate>
            <EditItemTemplate>
                <asp:TextBox ID="qtb" runat="server" Text='<%# Bind("numItems") %>' CssClass="qtb" />
            </EditItemTemplate>
        </asp:TemplateField>
        <asp:BoundField DataField="TotalItemPrice" HeaderText="Item Total" DataFormatString="{0:C}" ReadOnly="true" />
        <asp:BoundField DataField="orderID" ReadOnly="true" ControlStyle-CssClass="hidden" />
        <asp:BoundField DataField="itemID" ReadOnly="true" ControlStyle-CssClass="hidden" />
        <asp:CommandField ShowEditButton="true" />
    </Columns>
    <FooterStyle CssClass="cartFooter" />
</asp:GridView>

我如何在下面添加一行?我假设它会在代码后面，但我不知道该怎么做，因为这是我第一次使用asp.net。任何帮助都将非常感激。谢谢!

还有，如果我遗漏了什么有用的东西，请让我知道。就像我上面说的，我对这一切都很陌生。

在gridview的页脚创建一个新行

如果您想在页脚添加额外的行，您必须抓住OnRowDataBound事件

protected void cartGrid_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.Footer)
            {
                TableRow tableRow = new TableRow();
                TableCell cell1 = new TableCell();
                cell1.Text = "Add your your content here"; 
                cell1.ColumnSpan = 8; // You can change this. If you want different cells you can add as many cells as you need
                tableRow.Controls.Add(cell1);
                e.Row.NamingContainer.Controls.Add(tableRow);
                // You can add additional rows like this.
            }
        }

您需要这样做:

protected void GridView1_RowData(object sender,GridViewRowEventArgs e)
{
   if (e.Row.RowType == DataControlRowType.Footer)
   {
      TableRow tr = new TableRow();
      TableCell cell1 = new TableCell();
      cell1.Text = "A Button";
      TableCell cell2 = new TableCell();
      Button button = new Button();
      button.ID = "button1";
      button.Text = "Click me!";
      button.Click += new EventHandler(button_Click);
      cell2.Controls.Add(button);
      e.Row.Cells.Clear();
      e.Row.Cells.Add(cell1);
      e.Row.Cells.Add(cell2);
    }    
}
protected void button_Click(object sender, EventArgs e)
{
   String text = e.ToString();
}
