Asp.net 单击时禁用按钮，然后在刷新后启用

我在一个页面上有一个按钮，当单击该按钮时，会运行一个子按钮，用SQL表中的数据填充gridview。我正在用VB使用VS2010

当用户单击submit按钮时，我想立即禁用它，然后运行sub，一旦sub运行，再次启用按钮

我将下面的内容添加到按钮单击事件中，但它不起作用

        imgbtnComDetailGo.enabled = False

    Call Sub()
    imgbtnComDetailGo.enabled = True

它似乎不会立即禁用按钮

更新-我在谷歌上找到了这段代码

OnClientClick="this.disabled = true" UseSubmitBehavior="true"

---

但是它似乎没有调用SUB，因为除了按钮被禁用之外，没有任何事情发生。

从代码隐藏处将javascript附加到按钮（例如页面加载事件）：

如果您的页面具有验证程序，请在分配给按钮的OnClientClick之前，使用附加脚本包装上述sJavaScript：

sJavaScript = "if (typeof(Page_ClientValidate) == 'function') {if (Page_ClientValidate()) {" & sJavaScript & ";}}"

---

我已经用一些脚本完成了。以下是代码：

在实用程序文件中使用此选项，并在需要时调用

C#

在页面加载时，您只需调用

Util.SubmitDisable（这个按钮是NID）

CSS:

.ButtonPleaseWait { background: #F3F3F3 url('../images/pleasewait.gif') no-repeat 2px center; border: thin solid #000; width: 100px; height: 25px; color: #333; font-weight: bold; text-indent: 15px; font-size: 1.13em; }

asp.net

只需在asp.net按钮中使用
UseSubmitBehavior=“false”
，尝试使用ajax即可。我假设这是asp.net？好的-我已经添加了标记。对于将来的问题，请适当标记WinForms/ASP.NET/WPF等，因为这有助于获得正确答案没有问题，谢谢发布按钮1单击事件标记？
public static void SubmitDisable(System.Web.UI.Page source, ref System.Web.UI.WebControls.Button button)
        {
            string script = null;

            script += "if (typeof(Page_ClientValidate) == 'function')";
            script += "{";
