Disabled = true在后面的代码中不起作用 [英] Disabled = true does not work in code behind

问题描述

我有以下内容:

I have the following:

<button id="btnSend"  runat="server" alt="" CausesValidation="false"  onserverclick="btnSend_Click">

<img id="imgSend" alt=""  runat="server" src="~/Images/Buttons/send_ico.gif" 
align="top" />
<span><b class="va">Send Message</b></span>

</button>

我想禁用.

I would like to disable.

protected void btnSend_Click(object sender, EventArgs e)
{
    if (Page.IsValid)
    {
        btnSend.Disabled = true;
        System.Threading.Thread.Sleep(2000);
    }
}

这不起作用.

已修改:

我要做的就是禁用按钮，这样用户就不会单击两次.

this does not work.

Modified:

All I want to do is disable the button so it the user does not click twice.

private void InitializeComponent()
{
    this.btnSend.ServerClick += new System.EventHandler(this.btnSend_Click);
}

推荐答案

我不确定甚至没有Disabled 属性.尝试将Enabled 设置为false.

顺便说一句，如果您指的是HTML属性，则可能需要在客户端脚本中进行设置.

这是从客户端禁用按钮的示例:

I am not sure there''s even a Disabled property. Try setting Enabled to false.

BTW if you mean the HTML attribute, you probably need to set that in client side script.

Here''s an example of disabling a button from the client-side:

<input type="button" onclick="this.disabled=1">

有标记中的怪异字符:

ö nserverclick

There''s a weird character in the markup:

önserverclick

请尝试以下方式:

Please try it this way:

protected void btnSend_Click(object sender, EventArgs e)
{
    if (Page.IsValid)
    {
        btnSend.Attributes["disabled"] = "disabled";
        System.Threading.Thread.Sleep(2000);
    }
}

正如已经观察到的，ö应该是o.

干杯！

And as already observed the ö should be an o.

Cheers!
