I have a <script> that contains this line: var tbl = document.getElementById("<%= this.tblSelection.ClientID %>"); but tbl always ends up being set to null. The table is declared like this:
Ik keep getting this sort of errors when using Ajax controls.The colorpicker extender and the Cascaded dropdown generate this kind of error in my application.I have a scriptmanager in my masterpage.I already tried using a scriptmanager proxy.What could cause these errors?I have the controls inside template fields of data presentation controls.
I am working on ASP.NET 3.5, c#, visual studio 2010. I have made a master file and a default page that uses this master file. I have placed a couple asp:contentplaceholders in the master and corresponding code in the page that uses this master. I have also inserted JavaScript like this in the content page (and not the master):
On running the website I get the following runtime error in visual studio: Microsoft JScript runtime error: 'this.node' is null or not an object and it point to some function inside the JavaScript like this.node.onload=function(){..............//I am not a java guy so do not know much about this Where am I going wrong? Why does the site compile correctly but throw this runtime error? I also tried inserting this java code inside the master file in the <head>, but same error.
this code give that solution.but if any one of the field have null(example:r.urrQuickLinkRights contain the NULL) then only it will throw error like Object reference not set to an instance of an object.
i have an application wherein i have incorporate a "Remember Me" feature for the login screen. I do this by creating a cookie when the user logs in for the first time, so next time when the user visits the site i get the cookie and load the user information.
i have written the code for loading user information in a common class in the App_Code folder...and all my pages inherit from this class.
code for loading the user info is as follows:
public static void LoadUserDetails(string emailId) { UsersEnt currentUser = UsersBL.LoadUserInfo(emailId); if (currentUser != null) HttpContext.Current.Session["CurrentUser"] = currentUser; }
Now the problem is i get an "Object reference" error when i try to store the currentUser object in the session variable (even though the currentUser object is not null). However the password property in the currentUser object is null.
My site was woking fine, now i noticed that i get an error "Microsoft JScript runtime error: 'null' is null or not an object" when i checked the view source, i saw the following system generated code
<script type="text/javascript"> var Page_ValidationActive = false; if (typeof(ValidatorOnLoad) == "function") { ValidatorOnLoad(); function ValidatorOnSubmit() { if (Page_ValidationActive) { return ValidatorCommonOnSubmit(); } else { return true; } WebForm_AutoFocus('txtMailAddress');// --> IS THIS RIGHT???? out side the braces??? </script> </form> </body> </HTML>
I am declaring a list in my class, populating the list in page load and using the list in various methods in this class. But, I get this error at every instance where I use this list in the methods. Error: System.NullReferenceException: Object reference not set to an instance of an object.

I think thaAjaxControlToolkitTextBoxWrapperThis use to work, but I think that upgrading to te latest version of teh Toolkit (4 something) broke it:
var txtExpireYear = document.getElementById("ctl00_phPageContent_dtmPassportExpirationDate_txtYear"); txtExpireYear.AjaxControlToolkitTextBoxWrapper.set_Value(dtmDateOfExpire.getFullYear());
I now get the error:
Microsoft JScript runtime error: 'AjaxControlToolkitTextBoxWrapper' is null or not an object
I have developed my asp.net website in .NET 2.0 in other system where it is working fine. Now when I copied the asp.net website in my system and run it than I am getting the run time error:
Object reference not set to an instance of an object. public class FixURLs : IHttpModule { public FixURLs() { } #region IHttpModule Members public void Dispose() { // do nothing } public void Init(HttpApplication context) { context.BeginRequest += new EventHandler(context_BeginRequest); context.CompleteRequest(); }
some other logic. I am getting object reference error at the line: context.CompleteRequest(); My web.Config file has
I'm using a ScriptManager and including a webservice in the script generation. Upon calling the web service method via the javascript, I get the expected response except in IE 7/8. I get the error 'undefined' is null or not an object. I do not get this error in FireFox, Chrome and even Safari. The catch is, this is Microsoft's own generated code coming from the generated code from the script manager! This is the code that the error is thrown on:
I'm populating an object model with a linq query. The model looks like this:
MyModel{ DateTime AppointDate {get; set;} int TotalAppoints {get; set;} int AppointDuration {get; set;} }
The linq-to-sql query looks like that:
public static GetAppointsFromDB(params){ var MyQuery = from....where... select new MyModel{ AppointDate = ..., TotalAppoints = ..., AppointDuration =...}; return MyQuery as MyModel;}
In the master page, I'm looking to load the result of this query in the session like this:
if (Session["Appoints"] == null) {Session["Appoints"] = GetAppointsFromDB(...);}
When I run with the code, the session is always null. I added this line a second time, just right after, and the query runs again. When I'm looking to use the session at some other point in the code, it is null too there too. The query works because when I put a breakpoint on the return statement, I see the object properly filled.
iam using calender control in asp.net 2.0 as it is using master pages.. iam opening a window form content pages.. on window.close it is giving me null object as its not getting form name code on content page:

I recently converted my VS 2005 project code to VS 2008.My old code is running fine.
in my application for a module that displays detailed data in a tab control. I think I have determined the TabContainer1 is the name of the "This" element that is having the issue. I figured this out by debugging the ScriptResource.axd file. Here is the offending lines of code:
[Code]....
The way the app works is there are two modules that work together on the page. One is a selection grid and the other the detail form which shows the details from the selected item in the selection grid. If a user is in a limited role they can only see the data of the default selection and they do not see the grid to select from. It is under this circumstance that I get the error and the detailed module is not rendered. However if I break the code and skip over line 139 to line 140 the detailed information shows correctly. Otherwise I do not even see the detailed form. Based on that I know the detail form is working correctly but is not rendered after this error occurs. In addition I am using this same logic with another detailed pain that works correctly under both roles.
I can not seem to narrow in on any code that is causing the issue. For one thing I have no idea as to where the ScriptResource.axd is created. I also do not see where there is any settings for the tab control for submitions and I am not able to find an "OnSubmitStatements" in my code.
I have a asp.net page titled EstMaterials.aspx with a gridview that fills from a SQL table based on a parameter passed to it. The code for calling the form is below.
I have an a button field set as a link in a gridview. When the user clicks on the link it should open the "EstMaterials.aspx" page with a gridview listing the materials required for this job. If I do not have a parameter i.e, ScheduleWeek.oJob.JobSeqNbr, the gridview fills fine. However, with the parameter listed the gridview does not fill. It appears the form opens without ever looking at the parameter being passed.The page load event is below.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Not IsPostBack Then If Not IsNothing(ScheduleWeek.oJob) Then Dim tbl As New DataTable
I'm experimenting with validating forms in the asp.net MVC framework. I'm focusing on server side validation for the time being. I've come across an error that I'm not sure how to rectify. System.NullReferenceException: Object reference not set to an instance of an object. The code that throws the error is:
[AcceptVerbs(HttpVerbs.Post)] public ActionResult Create([Bind(Exclude="ID")] MembersCreate mc ) { mc.Modules = ModuleListDataContext.GetModuleList(); ViewData.Model = mc; //Validation using ModelState // // //line below errors when form field is empty // if ((string)mc.Member.Username.Trim() == "") ModelState.AddModelError("Member.Username", "Username is required."); if (!ModelState.IsValid) return View(); try { // TODO: Add insert logic here return RedirectToAction("Index","Home"); } catch { return View(); } }
When I put spaces in the field it performs exactly as i want, but if I leave the field blank and press submit I get the error. What's the best way to avoid this error and still validate blank form fields?
I have a Authorizeclient.aspx.cs page where I set my session value.Authorizeclient.aspx is a blank page. HttpContext.Current.Session["nodeID"]="0". This session value changes from 0 or non zero which depends on the value returned by Database. If no value is returned I assign HttpContext.Current.Session["nodeID"]="0" as the default state else I assign HttpContext.Current.Session["nodeID"]=resolve(nodeID).ToString()
Till this part it works fine as expected. However, I have a requirement that I need to read the nodeID from Session in other application on the same server. I mean this application too is part of the root project where I initially created the Session and set it. The strange thing is the Session["nodeID"] in application gets null "SOMETIMES" Not always. I am trying to read the Session in Page_Load. Sometimes it works fine and sometimes it gets null. Moreover the session object do not die and I can see other keys like Session["Themes"] etc there. The session is in InProc mode and have 20 minutes timeout time.
