c# - 如何从单元格内的控件获取表格行

Question

我的 Page.aspx 中有这个表

<asp:Table ID="table1" runat="server" CssClass="tabla" ></asp:Table>

我在我的 Page.aspx.cs 中使用 foreach 从列表动态构建 table1，添加 3 个单元格:

TableCell cell_name = new TableCell();
cell_name.Text = "Some name";
TableCell cell_active = new TableCell();
CheckBox checkbox = new CheckBox();
cell_active.Controls.Add(checkbox);
TableCell cell_actions = new TableCell();
ImageButton button = new ImageButton();
cell_actions.Controls.Add(button);

TableRow row = new TableRow();
row.Cells.Add(cell_name);
row.Cells.Add(cell_active);
row.Cells.Add(cell_actions);

table1.Rows.Add(row);

我希望我的 ImageButton 有一个 onClick 事件，并从那里获取被单击的我的 ImageButton 父行的表行 ID(表内索引)。那可能吗？有什么想法吗？

试试这个:

protected void Page_Load(object sender, EventArgs e)
{
        for (int i = 0; i < 3; i++)
        {
            TableCell cell_name = new TableCell();
            cell_name.Text = "Some name";

            TableCell cell_active = new TableCell();
            CheckBox checkbox = new CheckBox();
            cell_active.Controls.Add(checkbox);

            TableCell cell_actions = new TableCell();
            ImageButton button = new ImageButton();
            button.CommandArgument=i.ToString();
            button.Click += RowClick;
            cell_actions.Controls.Add(button);

            TableRow row = new TableRow();
            row.Cells.Add(cell_name);
            row.Cells.Add(cell_active);
            row.Cells.Add(cell_actions);

            table1.Rows.Add(row);
        }
}
protected void RowClick(object sender, EventArgs e)
{
        int rowIndex =int.Parse( ((ImageButton)sender).CommandArgument);
        Response.Write("RowIndex = " + rowIndex);
}
