asp.net - 将数据提交到数据库后从标签中删除文本

Question

我在按钮单击事件中有此代码。问题是我想在每次文本框得到验证和提交时显示文本“线程已成功添加”，并希望在提交后清除该标签。有没有办法做到这一点？

protected void BtnThread_Click(object sender, EventArgs e)
    {
        if (Page.IsValid)
        {
            LabelThread.ForeColor = System.Drawing.Color.Purple;
            LabelThread.Text = "Thread has been added successfully";
        }

        else
        {

            LabelThread.Text = "Thread couldnot not be added";

        }

        Thread obj = new Thread();
        obj.Insert_thread = TxtBoxThread.Text;

        int j = obj.insertmethod();

        TxtBoxThread.Text = "";

Answer 1

protected void Page_Load(object sender, EventArgs e)
{
  if (!IsPostBack)
   {

    }
   LabelThread.Text = String.Empty;
}

Answer 2

尝试写入没有 ViewState 的元素。我相信它的内容不会在回发后持续存在，只会在设置后立即出现。

ASPX：

<div id="MessageBox" runat="server"></div>

在您的 BtnThread_Click 事件中：

MessageBox.InnerText = "Thread has been added successfully";
