__dopostback无法按预期工作 [英] __dopostback not working as expected

问题描述

方案1(可行) 这是我创建的POC. 我有一个脚本管理器，一个HTML文本框，一个ASP.NET按钮，一个为上述按钮的Click事件设置了异步触发器的updatepanel.对于HTML文本框，我有onkeyup='__doPostBack('<%=ASPBUTTON.ClientID%>','').并且它的工作原理是，单击了按钮的Click事件，并且updatepanel被异步更新.

Scenario 1 (That Works) This is a POC i created. I have a script manager, a html textbox, an ASP.NET button, an updatepanel with async trigger set for Click event of above mentioned button. For html textbox i have, onkeyup='__doPostBack('<%=ASPBUTTON.ClientID%>',''). AND IT WORKS, the Click event of button is hit, and updatepanel is updated asynchronously.

方案2(不起作用) 与我的实际代码库的唯一区别是，我有一个JQUERY FILAMENTGROUP datetimepicker，其onchange事件被使用，而不是html文本框的onchange.此外，我的页面在这里使用母版页.现在，我的问题是，当datetimepicker的onchange事件触发时，请求进入服务器端，但BUTTON click事件没有触发.

Scenario 2 (It's not working) The only difference with my actual codebase is that i have a JQUERY FILAMENTGROUP datetimepicker whose onchange event is being used instead of html textbox's onchange. Further, here my page uses a master page. Now, my problem is that when onchange event for datetimepicker fires, the request goes server side, but BUTTON click event is not getting fired.

更多细节， 我想在选择datetimepicker时自动更新updatepanel.因此，该按钮实际上将通过CSS隐藏(显示:无).

Some more details, I want to update the updatepanel automatically on datetimepicker selection. So, the button would be actually hidden through css (display:none).

按钮ID-btnDateRangeCallback

Button id - btnDateRangeCallback

Datetimepicker文本框(非ASP控件)-dateRange

Datetimepicker Textbox (non ASP control) - dateRange

        onChange: function() {__doPostBack('<%=btnDateRangeCallback.ClientID%>',   $('#dateRange').val());}

[[请记住，我说过它是在我的POC简单化的情况下工作的，而在我的实际代码库中，我使用的是一个母版页来进行继承，因此所有这些控件都放在一个contentplaceholder中.此外，发生了回发，如果我在Page_Load处中断，我可以看到_EVENTTARGET和_EVENTARGUMENT已正确发送]

请帮助.

简而言之， 回发后，当我在Page_Load处中断时，我看到Request.Form内容为， ctl00％24ContentPlaceHolder1％24SMgr1 = ctl00％24ContentPlaceHolder1％24SMgr1％7cctl00_ContentPlaceHolder1_btnDateRangeCallback & __ EVENTTARGET = ctl00_ContentPlaceHolder1_btnDateRangeCallback & _ EVENTARGUMENT = 5％2f3％2f2011 +-+ 6％2f2％2f2011 & _VIEWSTATE =％2fwEPDwULLTE3NDY5NDIwMDRkZIuTqMNNsFHlRYhjpKaUCaCXj42h & _ EVENTVALIDATION =％2fwEWAgLBx52kBALP6Ln6DdkkwE％2frVIKQzKE1L0k4QhIc768w & _ASYNCPOST = true&

To put it more simply, After postback, when i break at Page_Load, i see the Request.Form contents as, ctl00%24ContentPlaceHolder1%24SMgr1=ctl00%24ContentPlaceHolder1%24SMgr1%7cctl00_ContentPlaceHolder1_btnDateRangeCallback &__EVENTTARGET=ctl00_ContentPlaceHolder1_btnDateRangeCallback &_EVENTARGUMENT=5%2f3%2f2011+-+6%2f2%2f2011 &_VIEWSTATE=%2fwEPDwULLTE3NDY5NDIwMDRkZIuTqMNNsFHlRYhjpKaUCaCXj42h &_EVENTVALIDATION=%2fwEWAgLBx52kBALP6Ln6DdkkwE%2frVIKQzKE1L0k4QhIc768w &_ASYNCPOST=true&

为什么不是btnDateRangeCallback击中的Click事件?

Why is not Click event for btnDateRangeCallback hitting???

推荐答案

使用UniqueID代替:__doPostBack('<%=btnDateRangeCallback.UniqueID %>', ...

Use the UniqueID instead: __doPostBack('<%=btnDateRangeCallback.UniqueID %>', ...
