I designed a user control. It contains a public property "CurrentValue". When I try to initialize the property using an Eval expression, a null value is assigned.
// In below code, label assignment is OK, RatingNull user control assignment get null
I just recently uploaded my site in web hosting, soon as it was live, I found out that the Ajax was not initializing or not working.
I look into javascript error log, and its pointing at
Sys.WebForms.PageRequestManager._initialize('ctl00$ToolkitScriptManager1', document.getElementById('aspnetForm'));Am I missing something, or is this issue can only be resolved by my hosting? My concern is since AjaxControlToolkit is a class DLL, it should not be a problem right?
I have been trying to get a mysql database to connect to visual studio 2008 so I can use the ASP.net administration tools. I have researched this error for two days now and have tried every suggestion I could find. I am not 100% sure where the .dll's belong but I am pretty sure they are in the correct place and incase not I have added them into a bin folder inside my web application. the only other thing I can think is that maybe my mysql and mysql connector versions dont match. I am currently using mysql version 5.1.54 and my connector version is 6.3.6.0. Also I have successfully conencted to my database in the server explorer and it has already autogenerated the necassary tables into my database. It says my error is on line 59 so here is the code associated with my line 59.
I am trying to implement a super simple MySQL membership. All I want my Membership class to do is ValidateUser. Here is my method:
[Code]....
When I try loggin in, I get the following error: I have added the MySQL.Web and MySQL.Data references. I also have auto generate schema set true. What am I doing wrong ? Here is my Users table (created by myself), where the user login details are saved:
I have a custom control that inherits from .NET's CompositeControl class. This control overrides the CreateChildControls in order to build its child controls dynamically. I need the page to post back after a couple different javascript events occur on the client side.
In order to accomplish this, I create two hidden controls on the page so I can set their values with javascript, submit the page, and read the values out on server side. Here's is the code I use to create these two hiddens:
Even though I can see that Application.CreateDate has been set in the Page_Load method on the containing UserControl, the code-behind in the DDL never seems to pick it up.
This is even the case with ValidityDate="<%# DateTime.Now %>". The property of the DDL is declared like this:
[Category("Data")] [DefaultValue(null)] public DateTime? ValidityDate { get; set; }
what is the correct sequence I should be following here. I thought that a DDL would evaluate a cynamic property value like that without too much trouble.
i am unable to change the selectedindex property to 0 it is coming as -1 only and the code wat i am using is
if (lstintellisense.SelectedIndex.ToString() == "-1") { lstintellisense.SelectedIndex = 0; }
after making 0 also its remaining as -1 only and i am getting exception as InvalidArgument=Value of '0' is not valid for 'SelectedIndex'. Parameter name: SelectedIndex
I'm trying to programmatically set the property of a control on my Form AFTER I've proccessed an update command using the FormView, but it's not working. In my example below, I have a basic FormView with only a TextBox and Label in its EditItemTemplate. The FormView uses an AccessDataSource. The TextBox is bound to the datasource, but the label is not. What I'm trying to do is update the value in the TextBox (as well as its associated data stored in the database), and then change the Text property of the Label. (*Note: that I using the label purely as an example. The point is I can't see to set any control's property after an update).
I initally thought it had something to do with the "Page.IsPostBack", but even after trying to adjust my code for that, its still not working. I've tried change the Text property during the Page.IsPostBack during Page_Load event. I've tried setting the Label's EnabledViewState property to True and to False. I've tried using the FormView's OnItemUpdating and OnItemUpdated events. I've tried using the DataSource's OnUpdating and OnUpdated events.
I don't seem to be able to set the Text property within this custom control. Even though I set the Text property in code-behind, when I refresh the web form, only the default message is shown.
I have ajax accordion with 6 panes with an user control inside each of it. In the first pane I have a form view user control and have a modalpopup to display error message. The same method is used in all other panes.
On page load I was able to set the label text property and it properly shows in modal popup.
However whenever I do some validation and update label text property, the modal popup shows up but the label text property is not updated. It works in all other panes.
The only difference is the user control in the pane is inside of a update panel. If I remove the update panel every thing works fine. But I need the update panel to avoid full post back.
How do I set the label text property inside of a modal popup.
I am having a problem with the Client Validation not firing when I have marked a nullable DateTime field as [Required] and the value of the field is null. (It is actually stopping ALL client validation on the page working - not just the DateTime field).
Interestingly enough, once a post back has been done and the error picked up on the server, the client validation starts working.
Also if you set the date to a none null value (see commented out line in the controller) it will also work
I have replicated this behaviour in a small test project (this is deliberately very Noddy - just enough to replicate the problem)
Am I doing something fundamentally wrong or am I looking at coding some sort of work around here? (I realise that a Required nullable field sounds like a bit of a oxymoron, but I wanted to present the user with a blank field which they must then fill, not one pre-populated with an arbitrary date value)
Im using two stored procedures to write and update values in a SQL DB. Im using the SQLDatasource update method. When I run the webpage on my development server everything runs fine. When I try and run the web page on my Live server I get the following error :System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding This always takes 30 seconds to fail - and looking at google it seems that this is a connection timeout error.In my web.config file I have updated the connectionstring line to include a timeout setting :
I want to create my own naming convention for page events rather than AutoEventWireUp but I couldn't find Component Initialize methods any where ? Should I override it ? But in which class it is defined ?
Edit :
For example : I don't want to use Page_Load but LoadThisPage naming. So It should be like
Load += new LoadThisPage(sender,e);
I was expecting a InitializeComponent method where I can initialize page,controls etc. events handlers...But it turned out to be Constructor function :
So what confused me is I thought there should have been a method like InitializeComponent which does things for me already created by Designer itself so I thought I could define my own event handler names within this method by overriding it in the say Default.aspx.cs .
I have - for instance - an asp:FormView which supports Read, Insert, Update, Delete and is bound to a DataSource:
[code]....
If I am in Read-Mode or Edit-Mode the control is initialized with the property MyText of the current object which is bound to the FormView.
But when I go to Insert-Mode I do not have a "current object" (FormView1.DataItem is indeed null) and the controls are empty.
If I want to have my TextBox control initialized with a specific value how can I do that? In which event can I hook in to set default values to the controls in the InsertItemTemplate?
Especially I have in mind using an ObjectDataSource. I was expecting that the InsertItemTemplate is initialized with a business object which underlies my ObjectDataSource and which is created by the ASP.NET framework simply by using its default constructor when the InsertItemTemplate gets activated. In the default constructor I would init the class members to the default values I'd like to have in my controls of the InsertItemTemplate. But unfortunately that's not the case: No "default" object is created and bound to the FormView. So it seems I have to initialize all controls separately or to create the default object manually and bind it to the InsertItemTemplate of the FormView. But how and where can I do that?
While in constructor i am gettine error, Aobj(0).type is not initialized, it says that Object reference not set to an instance of an object. how to initialize my objects?
I was looking for a custom membership/role provider and came across The Altairis Web Security Toolkit Looked at the source and this is just perfect for what I had in mind. So I implemented it in my project, created a database and tables and configured it in my web.config. Everything compiles fine, but seems I'm being stupid in how to actually use it. (Looking at the source code here might be useful in helping me out) Just to see it work, I'm making a call like this:
Code: private readonly KrokSqlMembershipProvider_membershipService; _membershipService = new KrokSqlMembershipProvider(); MembershipCreateStatus status; _membershipService.CreateUser("krok", "password", "[URL], "", "", true, null, out status);
However when I debug the code, I realize that in the MembershipProvider class the configuration settings to be loaded from the web.config are empty, so it fail when trying to connect to my database (empty connection string). I notice the settings are retrieved in the Initialize method, but I'm not sure if I'm suppose to call that, and if so, how. (The sample application that comes with the source code have no code in it. It's asp.net, while I'm using asp.net mvc)
I am getting the error Configuration System Failed to Initialize , i have two projects inside my solution and Listed belwo is the app.config for each of them
I have a site that uses ActiveRecord. I'm getting an exception that says "An ActiveRecord class () was used but the framework seems not properly initialized. Did you forget about ActiveRecordStarter.Initialize() ?" This is a web application, and the Initialize() method is called by the Application_Start event handler.
I created a new page that also calls the initialize() method. If I visit that page once, then the rest of the site works. If I visit it a second time, I get an exception stating that the Initialize() method can only be called once.
I've tried modifying the web.config and resetting the application pool to force Application_Start to run.
This only happens in production; dev, my stage, and client stage are fine. Production is the only load-balanced environment--I'm not sure if that comes into play.
Edit: We have another site deployed in the same environment which successfully uses ActiveRecord with the same initialization code. One difference is that the site that is working has only the ActiveRecord code in Application_Start; the site that doesn't also sets up some URL routing in Application_Start.
