updatepanel

问题 My drop down list resets to default when I try to select a item, and it also doesn't trigger's code behind method when I put a line break and try to debug it: Here's markup, <script type="text/javascript"> function bringPOPup() { $.blockUI({message: $('#anotherUP'), css: { width: '600px' } }); } </script> <div id="anotherUP" style="display: none; cursor: default"> <asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="false"> <ContentTemplate> <asp

问题 I have run into what seems to be a very famous problem: My updatepanel fires a full postback instead of a async postback. The normal solution is to give all controls you add dynamically an ID, which I have done, but I still get a full postback instead of my async postback... Here's the code: HTML: <asp:UpdatePanel ID="ItemsUpdatePanel" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="False"> <Triggers> </Triggers> <ContentTemplate> <asp:ListView ID="PlayerItems" runat="server"

问题 Folks, I'm working on a rather complicated site. We have an update panel that contains some controls. When one of the controls is clicked, a jQuery dialog box opens. When the dialog box closes, I want to signal the update panel to change its display. To do that I need to post back to the update panel. I know the dialog box has a handy callback event that you can hook up to. But here's the thing. The javascript that manipulates the dialog is all in a separate .js file. I want to continue

问题 I have an update panel that has UpdateMode of Conditional and ChildrenAsTriggers set to false. I only want a few controls to cause an asynchronous postback: <asp:UpdatePanel ID="updPnlMain" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="false"> <ContentTemplate> // ... <asp:Repeater ID="rptListData" runat="server"> <ItemTemplate> <asp:Button ID="btnAddSomething" runat="server" OnClick="btnAddSomething_Click" /> </ItemTemplate> </asp:Repeater> // ... </ContentTemplate> <Triggers>

问题 I'm using jQuery UI's draggable and droppable libraries in a simple ASP.NET proof of concept application. This page uses the ASP.NET AJAX UpdatePanel to do partial page updates. The page allows a user to drop an item into a trashcan div, which will invoke a postback that deletes a record from the database, then rebinds the list (and other controls) that the item was drug from. All of these elements (the draggable items and the trashcan div) are inside an ASP.NET UpdatePanel. Here is the

问题 How can I tell if a method is running in the context of an AJAX postback (i.e as the result of a UpdatePanel (asynchronous) postback)? According to egoldin Page.IsAsync is a very common confusion that has absolutely nothing to do with AJAX. The correct approach is to use ScriptManager.GetCurrent ( Page ).IsInAsyncPostBack. 回答1: Use ScriptManager.GetCurrent ( Page ).IsInAsyncPostBack 来源： https://stackoverflow.com/questions/265686/how-can-you-tell-if-a-method-is-being-run-in-updatepanel
