C# 在ASP Web表单中基于链接按钮单击显示/隐藏项目？

我一直在努力让这个代码正常工作，但就我的一生而言，我无法理解它。我在GridView中有一个LinkButton，我点击它，它填充另一个GridView和一个Repeater。我的问题在于第二个GridView下面的项目。我有两个链接按钮、一个标签和一个文本框，我需要在显示第二个gridview之前将其隐藏。到目前为止，我已尝试设置“Visible=false”，并在单击LinkButton后在代码中切换为true，但没有显示任何内容，我也尝试过关闭验证和其他一些功能，但到目前为止运气不佳，这是我最后一次尝试：

网页表单代码：

任何解决方案都将不胜感激

你能显示你的页面加载代码吗？页面加载当前为空。链接按钮后面的代码是否执行？我没有你的对象数据源，因此无法运行代码，但我创建了一个按钮并添加了ForceClose行。Visible=true；点击事件，链接对我来说很好。我建议将问题缩小一点。我想我的问题是我设置了一些东西，它通过一个查询字符串传递。。。我不知道我现在是如何设置这个LinkButton的，虽然我需要它在我点击按钮到页面上的另一个gridview时传递一个特定的值。。

protected void LinkButton1_Click(object sender, EventArgs e)
{
    ForceClose.Visible = true;
    ReceiveButton.Visible = true;
    ReasonLabel.Visible = true;
    ForceCloseTextBox.Visible = true;
}
