问题 I have two buttons: <asp:Button ID="Button1" runat="server" Text="Button" /> <asp:Button ID="Button2" runat="server" Text="Button" /> How can I determine on pageLoad which one of this two caused the postback? Is there a short solution as I know there are only two controls that can cause this postback? 回答1: You can use this method to get the control that caused the postback: /// <summary> /// Retrieves the control that caused the postback. /// </summary> /// <param name="page"></param> ///

jQuery modal form dialog postback problems

I know there are quite a few articles based on using the SimpleModal plugin, and I have tried to adapt these and override the _doPostback function, but with no joy. I think the problem is within the call to my __doPostBack function and what the parameters should be. Is that the case? Here\'s my form <form id=\"summaryForm\" runat=\"server\"> <div id=\"dialog\" title

I know this question has been asked thousands of times, and I've struggled with it before, but for some reason, I can't accomplish what I want to accomplish... I have a dynamically added LinkButton that when clicked will dynamically add a control (in this example, a textbox) to the same panel. The intent is to continuously add on as many controls as times the LinkButton was clicked (i.e. I click it once, one box, then another click will give me 2 boxes, another click adds a 3rd). In the code below, I use the current date and time serialized to create a unique ID for each textbox control. When

I have a button like the following, <asp:Button ID="pagerLeftButton" runat="server" OnClientClick="disable(this)" onclick="pager_Left_Click" Text="<" /> When I use my button like that, onclick is not firing. When I remove OnClientClick, then onclick is firing. What I need to do is, disable the button during the postback and enable it after the postback ends. Edit: Additional information: I added break point to my firing functions is c# part and I am debugging, they are not firing for sure. Those functions are like protected void pager_Left_Click(object sender, EventArgs e) { //Do smthing. }
