scriptmanager

问题 We use asp.net webform to develop our outlook web add-in. There has been an issue in the add-in when a postback occurs inside an updatepanel, some client side errors will be thrown and it will make the add-in malfuntions. This issue is quite intermittent and we never found a solution. One of the error is like this h is not a constructor I have managed to strip down the add-in to its most simple form possible, where only the office.js and the scriptmanager are present. It can be observed that

One thing I needed to do was to populate some form controls with data returned from the Web API. I used JQuery for this. Now, when I run the application and submit the form, I get an error indicating that the page had been updated: Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in

问题 Can somebody look at the below code and tell me what I am doing wrong. for(i=0;i<=Request.Files.Count;i++) { int percentComplete = (int)Math.Ceiling((double)(i + 1) / (double)Request.Files.Count * 100); string message = string.Format("{0} of {1} uploaded", i + 1, Request.Files.Count); ScriptManager.RegisterStartupScript(this, this.GetType(), "progress", @"do_progress("+message+","+percentComplete+");", true); } I am trying to update the client with each pass of the loop. On the client (inside

问题 I am having what I believe should be a fairly simple problem, but for the life of me I cannot see my problem. The problem is related to ScriptManager.RegisterStartupScript, something I have used many times before. The scenario I have is that I have a custom web control that has been inserted into a page.
