如何通过itemCommand启用Repeater的itemtemplate中的所有文本框控件？

Question

我有一个中继器，我使用标签进行显示，并使用一个隐藏的文本框来保存相同的值。现在我想启用文本框，以便用户可以编辑表/中继器中的输入。谁能帮我？下面是我的代码

public void FillTable()
{

    DataTable table = new DataTable();
    using (MySqlConnection conn = Functions.GetConnection())
    {

        string sql = "SELECT FirstName, LastName from tbluser LIMIT 15";



        using (MySqlCommand cmd = new MySqlCommand(sql, conn))
        {
            MySqlDataAdapter da = new MySqlDataAdapter();

            da.SelectCommand = cmd;
            da.Fill(table);
            conn.Close();
        }
    }
    asd.DataSource = table;
    asd.DataBind();
}
protected void Button1_Click(object sender, EventArgs e)
{
    asd.Visible = true;
}

protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
{
    RepeaterItem item = e.Item;

    Literal lblname = (Literal)item.FindControl("Label2");
    TextBox txtbox = (TextBox)item.FindControl("Label3");




    if (e.CommandName == "EDIT")
    {
            lblname.Visible = false;
            txtbox.Visible = true;

Answer 1

您没有获得文本框，而是两次获得标签：

 TextBox txtbox = (TextBox)item.FindControl("Label3");
