点击后禁用按钮，然后在刷新后启用

我在页面上有一个按钮，当点击时该按钮运行一个使用SQL表中的数据填充gridview的子组件。我在VB中使用VS2010。点击后禁用按钮，然后在刷新后启用

当用户点击提交按钮时，我想立即禁用它，然后运行子工具，一旦子工具运行，再次启用按钮。

我添加了下面的按钮单击事件，但它不工作

 imgbtnComDetailGo.enabled = False 

    Call Sub() 
    imgbtnComDetailGo.enabled = True

它似乎并没有被立即禁用按钮。

更新 - 我发现谷歌

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

这个代码，但它不会出现调用SUB从按钮被禁用没有任何反应分开。

尝试使用Ajax来做到这一点。 –

我认为这是ASP.NET？ –

是的，这是正确的 – Silentbob

附加一个JavaScript的按钮从后面的代码（如Page_Load事件。）：

sJavaScript = "this.value='Please wait...';" ' optional button text 
sJavaScript &= "this.disabled = true;" 
sJavaScript &= Page.ClientScript.GetPostBackEventReference(imgbtnComDetailGo, "") 

imgbtnComDetailGo.OnClientClick = sJavaScript

如果你的页面有验证，包装与其他脚本上面sJavaScript分配到该按钮的OnClientClick这个前：

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

我已经用一些脚本完成了这个。这里是代码：

使用这个在您的实用程序文件并调用时，你需要

C＃

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 += "{"; 
      //script += " /if client-side does not validate, stop (this supports validation groups)"; 
      //script += " //however before validating attempt, must save and, then restore the page validation/submission state, otherwise"; 
      //script += " //when the validation fails, it prevents the FIRST autopostback from this/other controls"; 
      script += " var oldPage_IsValid = Page_IsValid;"; 
      script += " var oldPage_BlockSubmit = Page_BlockSubmit;"; 
      script += " if (Page_ClientValidate('" + button.ValidationGroup + "') == false)"; 
      script += " {"; 
      script += "  Page_IsValid = oldPage_IsValid;"; 
      script += "  Page_BlockSubmit = oldPage_BlockSubmit;"; 
      script += "  return false;"; 
      script += " }"; 
      script += "}"; 

      //script += "//change button text and disable it"; 
      script += "this.className = 'ButtonPleaseWait';"; 
      script += "this.value = 'Working ...';"; 
      script += "this.disabled = true;"; 

      //script += "//insert the call to the framework JS code that does the postback of the form in the client"; 
      //script += "//The default code generated by ASP (WebForm_DoPostbackWithOptions) will not "; 
      //script += "//submit because the button is disabled (this is new in 2.0)"; 
      script += source.ClientScript.GetPostBackEventReference(button, null) + ";"; 

      //script += "//MUST RETURN AFTER THIS, OTHERWISE IF THE BUTTON HAS UseSubmitBehavior=false"; 
      //script += "//THEN ONE CLICK WILL IN FACT CAUSE 2 SUBMITS, DEFEATING THE WHOLE PURPOSE"; 
      script += "return true;"; 

      button.Attributes.Add("onclick", script); 
     }

在页面加载你只需要调用Util.SubmitDisable(this,buttonID);

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

只使用UseSubmitBehavior="false"在asp.net按钮
