问题 I want do disable postback after clicking a <asp:Button> . I've tried to do that by assigning onclick="return false" , but in the button doesn't work.

You need to use the OnClientClick handler such as <asp:button OnClientClick="return false;" /> 回答3: Seeing as

问题 Recently, we tested our products on IE10 and encountered a problem about that server button control “Asp:ImageButton” are not be fired on IE10 with UpdatePanel.

问题 My Question I managed to answer myself, however the same set of functionality has another problem. For some reason the first postback of the save event of the posted file hits the Ol' Object not set to an instance of an object error, but on the second attempt of uploading a file and firing my save event (converts to byte[] an stored as SQL Server BLOB) it does everything is supposed to do. Same problem here There is a good suggestion of using the AJAX AsyncUpload control however I am a firm

问题 I am working on rewriting URLs Urlrewriting.net, and have run into what seems to be a common problem but I can seem to fix it. I'll present a simplified case. The URL rewriting is working perfectly with the rule: <urlrewritingnet rewriteOnlyVirtualUrls="true" defaultPage="default.aspx" defaultProvider="RegEx" xmlns="http://www.urlrewriting.net/schemas/config/2006/07"> <rewrites> <add name="catalog" virtualUrl="^~/catalog/(.*)/(.*).aspx" rewriteUrlParameter="ExcludeFromClientQueryString"

问题 I am having trouble posting a form that contains a Dictionary that contains an int as a key and a list of objects as a value. Originally this was just a List of Objects and that worked fine and the type was: List<MyObject> Fields the working markup was Fields_{0}__Property1 where {0} is the index of the object. To get it to post back the List of Objects I rendered the object with hidden fields like this: @Html.HiddenFor(m => m.Property1, new { Name = string.Format("Fields[{0}].Property1",

If I was to do a Post with a button, or some other server-side control, then would the event be triggered. After much debugging I found the following Javascript error was being thrown every time I selected something

问题 I would like to know if there is an equivalent of IsPostBack in PHP. I want to call a function or a method only once, once the user is logged in. I have a facebook application, in which once the user authorizes the application it should enter his details in the database. This basic stuff should have been done using the post-authorize callback url which facebook pings when the user first authorizes the app. The issue is that since I am checking whether the user exists or not in index.php, I
