Asp.net 在gridview的最后一列添加删除按钮

我正在

网格视图上动态添加列

DataTable dt1 = new DataTable();
dt1.Columns.Add("Item Title", typeof(string));
dt1.Columns.Add("Unit Pack", typeof(string));
dt1.Columns.Add("Pack", typeof(string));
gv1.DataSource = dt1;
gv1.DataBind();

并自动添加

删除按钮

<asp:GridView ID="gv" runat="server">
    <Columns>
        <asp:CommandField ShowDeleteButton="true" />
    </Columns>
</asp:GridView>

现在我想在最后一列显示Delete按钮，如

| Item Title | Unit Pack | Pack | Delete |

我该怎么做？如何在最后一列创建删除按钮

<asp:GridView ID="gv" runat="server" AutoGenerateColumns="False">
    <Columns>
        <asp:BoundField DataField="Item Title" HeaderText="Item Title" />
        <asp:BoundField DataField="Unit Pack" HeaderText="Unit Pack" />
        <asp:BoundField DataField="Pack" HeaderText="Pack" />
        <asp:CommandField ShowDeleteButton="true" />
    </Columns>
</asp:GridView>\

尝试以下代码

您正在动态添加列，这就是为什么您需要添加动态删除列。也可以在RowDataBound中添加linkButton：

protected void gv_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.DataItem != null)
{
    LinkButton lb = new LinkButton();
    lb.CommandArgument = e.Row.Cells[3].Text;
    lb.CommandName = "Delete";
    lb.Text = "Delete";

    e.Row.Cells[3].Controls.Add((Control)lb);
}
}

在rowCommand中，您可以编写删除代码：

protected void gv_RowCommand(object sender, CommandEventArgs e)
{
switch (e.CommandName.ToLower())
{
    case "delete":
//your code here
        break;
    default:
        break;
}
}

在gridview的RowCreated事件中，可以将CommandField推到右侧：

protected void gv1_RowCreated(object sender, GridViewRowEventArgs e)
{
    GridViewRow row = e.Row;

    TableCell cell = row.Cells[0];
    row.Cells.Remove(cell);                
    row.Cells.Add(cell);
}

多亏了这一点

签出SetOrdinal属性-可以在这里找到示例，您是否在运行该页面后检查

删除

按钮对齐方式，或者只检查其设计部分（无需运行或调试）。请快速回答。这不是动态的：/

protected void gv_RowCommand(object sender, CommandEventArgs e)
{
switch (e.CommandName.ToLower())
{
    case "delete":
//your code here
        break;
    default:
        break;
}
}

protected void gv1_RowCreated(object sender, GridViewRowEventArgs e)
{
    GridViewRow row = e.Row;

    TableCell cell = row.Cells[0];
    row.Cells.Remove(cell);                
    row.Cells.Add(cell);
}
