如何在c#中从单元格中获取值

本文关键字：单元格 获取 | 更新日期: 2023-09-27 18:15:29

我有一个表格，每行包含一个按钮。如果单击该按钮，我希望从该特定行的第一列检索值。这是我的代码，我怎么能这么做。谢谢你

    foreach (var c in list)
        {
            TableRow row = new TableRow();
            TableCell c0 = new TableCell();
            c0.Text = string.Format("<img src='"+c.Movie_poster+ "'/>");
            TableCell c1 = new TableCell();
            c1.Text = c.Name;
            TableCell c2 = new TableCell();
            c2.Text = c.Date.ToStirng();
            TableCell c3 = new TableCell();
            c3.Text = c.desc;
            TableCell c4 = new TableCell();
            c4.Text = c.genre;
            TableCell c5 = new TableCell();

            //Add each string to cell in row
            row.Cells.Add(c0);
            row.Cells.Add(c1);
            row.Cells.Add(c2);
            row.Cells.Add(c3);
            row.Cells.Add(c4);
            row.Cells.Add(c5);
            //Add the row to the table
            Table.Rows.Add(row);
            Button getname = new Button();
            getname.Text = "Reserve";
            getname.Click+= new EventHandler(getname_Click);
            c5.Controls.Add(getname);
        }

    }
    protected void reserve_Click(object sender,EventArgs e)
    {
        Button btn = (Button)sender;
        TableRow row = (TableRow)btn.
        string name = row.Cells[1].Text;
        lbl.Text = name;
    }

如何在c#中从单元格中获取值

在创建按钮之前，应该写一个带有行号的新属性。

    //Add the row to the table
    Table.Rows.Add(row);
    Button getname = new Button();
    getname.Attributes.Add("idRow", idrow);
    idrow += 1;
    getname.Text = "Reserve";
    getname.Click += new EventHandler(getname_Click);

然后在你的reserve_Click中，你应该得到的行ID存储在按钮属性

 Button btn = (Button)sender;
 int idRow = int.Parse(btn.Attributes["id"]);
 TableRow row = t.Rows[idRow];

您可以将Column的值作为CommandArgument绑定到Button。

Button getname = new Button();
getname.Text = "Reserve";
getname.CommandName = "Reserve";
getname.CommandArgument = "Column Value";
getname.Command += new CommandEventHandler(Button1_Command);

然后在按钮命令

protected void Button1_Command(object sender, CommandEventArgs e)
{
    if (e.CommandName == "Reserve")
    {
        string columnValue = e.CommandArgument.ToString();
    }
}
