I have a rather large application that has literally a hundred DDLs with Yes / No ListItems. In an attempt to save myself some time, I created a custom control that extends the standard DDL.It all seems to work fine but I am having some issues when assigning the SelectedValue property in code where the selected value does not seem to have an affect on the control. I wonder if I should be adding my items during Init or PagePreLoad? Should I be calling base.OnInit before or after I add the list items? This mostly works but not 100%. (v3.5)
public class YesNoDropDownList : DropDownList
{
protected override void OnLoad(EventArgs e)
What would be the best way to extend the EntityDataSource control? I have a site that implements Entity Framework and I current create my model container and add it to the HTTPCurrent context. When I create EntityDataSource controls on the page I have to go into the code behind and set the OnContextCreating to add MY context to the EntityDataSource instead of the one that EntityDataSource creates. This is because in my model I have extended the Partial Classes to support Validation and custom Save/Delete methods.I would ideally like to create a custom control that I can drop onto a page that has its context already set to the context that I created.
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="CustomPanel.ascx.cs" CodeFile="CustomPanel.ascx.cs" CodeFileBaseClass="System.Web.UI.WebControls.Panel" Inherits="MyProject.CustomPanel" %> ... namespace MyProject { public partial class CustomPanel : System.Web.UI.WebControls.Panel { ... } }
However, I'm really not sure how to proceed from here, because this does not appear to follow a logical inheritance path that includes System.Web.UI.UserControl / Am I doing something wrong? How can I inherit Panel and extend standard event-handlers, such as PreInit?
I'm trying to extend de GridView control with a Custom Server Control, I'm doing ok with extended properties but when I get to methods that need to re-apply or modifiy the DataSource I don't get any data in the grid, though the SQLDataSource actually retrieve data. Here is my MyGridView.applyFilter() method, which should filter the data but actually shows an empty GridView, but as I sayed, the DataSource has data. I try to find (FindControl) theSQLDataSource of the GridView (Me) and modifiy its paramters, thenDataBind Me to apply the changes...
I'm trying to extend the GridView into a custom/user control "WorklistGridView". And I'm not quite sure how to do it... so here's what I need:Every row needs to have a control (either a boundfield or a templatefield with a label, etc.) that contains the StepID (which is a column returned in the data set).I want to be able to use the WorklistGridView as a base class and extend it to something like "XyzWorklistGridView", where that child class would have a few more controls in the row template.
I've created loads of user controls, but this is my first time dealing with extending a server control. The problem I'm getting is that the base control's data is not being persisted across postbacks in a Master/Content page.I'm actually trying to get this working using a Telerik control (for my sins), but the same issue happens with a standard Web TextBox control. Code:
[Code]....
Now, I've copied the way I handle the control state as I do it with user controls (ControlState), and it isn't working. Can someone point me in the right direction please? All the examples I find refer to creating user controls, not extending existing controls. Specifically why nothing is being persisted on post back.
I had use a combox to let user select staff name and then it will automatically retrive the responsible recommending officer and approving officer to display in other 2 dropdownlist.
my code works fine but when user select staff name each time, the page will reload once to refresh the dropdownlist.
user complaint and don't want the page reload every time, how can i disable the postback? I need to use ajax?
I've been recently tasked with leading an effort to improve our input (and output) validation with OWASP recommendations and PCI compliance in mind. In the process, I'm trying to assess the value of the ESAPI.NET project which does not appear to have seen any activity since the spring of '09 and as it stands is incomplete.
Does anyone have experience using or extending ESAPI.NET v0.2? Is it a good starting place today for building out an infrastructure to address the targeted vulnerabilities?
FYI: I am looking at MS AntiXSS which, of course, only addresses a portion of ESAPI's scope. We already do a good job with SQL injection though there are improvements we need to make.
The GetRolesForUser() method in the RoleProvider takes the user login name and returns the list of roles for that user. But in my application this is not enough, I need a few more pieces of information to be able to get the user's roles. How can I get this extra information into the method? I have it in the Session, but I found out that Session is not available in the RoleProvider.
What I had in mind was putting this extra info in some class that extends MembershipUser, assuming I can get to it inside the RoleProvider. But I don't know how to create the CustomMembershipUser and make it part of the MembershipProvider. Is this even possible? The easy way out would be using cookies, but I'm trying to keep away from it.
When you create a webpage in ASP.net, the codebase inherits System.Web.UI.Page
Now when I extend the page object to check for SessionExpired for example, I create a new class and inherit from system.web.ui.page, and overwrite some functions.
The problem then is that on each page, I have to replace system.web.ui.page with my custompage class.
Is there a way to extend a class by adding methods or modifying its methods directly (e.g. add the sessionExpired check to System.Web.UI.Page) ?
I use two different collapsiblepanelExtenders with similar colapsedControlID which is not a matter here. ince both of them working but with some misbehaviour, for example if the first one is open and I click wherever on it , the second one extends. also by clicking on the second one it collapses.That means that some how an event triggers and makes them collapse or extend.I have a kind of editing panel inside each extandedPanel which are used to update something on the page. the problem is that by clicking on eachtextbox or fileupload, the second panel collapses again. before any other action. So that I can not enter the textboxes. I can do that if I use tab button on keyboard. but that sucks really.
[Code]....
it might be because the second extender is inside the collapsible panel itself. but why it doesn't stay in extended state?
I have been developing a pure MVC CMS for fun and have run into an annoying bug/feature of ASP.NET routing.Each dynamic managed page in my CMS is associated with a particular route that is pulled from the database. These are loaded at app start. When a user adds a new page or edits the Url of an existing page I need to be able to edit the RouteTable to insert/edit route accordingly.The problem is that the new route does not need to be simply added to the end of the RouteCollection, instead it may need to be inserted into a particular position. Seems logical enough except that the RouteCollection contains only a standard Insert(int idx, RouteBase route) method inherited from Collection<T> which doesn't contain the route name. The name of the route is important as I use it throughout to generate action links.Looking at reflector I can't see an easy way to extend this collection as the _namedMap dictionary is marked as private. I tried chopping the collection at the point of insert and re-adding each item again, however because there is no method to reverse lookup a route's name from the RouteCollection I cannot re-add them with the name they may have had before. So frustrating!!!Why is the name of the route not a property of the route object?Why if MS is serious about us extending MVC and Routing do they make crucial classes hard to extend?Any suggestions as to the best solution here?Edit :Ok maybe I should have been much much clearer here. I am not looking for a critique of my CMS design. I appreciate the comments but this is not what I am asking.
I were following the tutorial at this page of how to build my own view engine: [URL] And in hope of just extending the existing RazorViewEngine I made some changes to the code in the tutorial...
[Code]....
The thing is that now when I run my site..I get the following error: CS0246: The type or namespace name 'WebMatrix' could not be found (are you missing a using directive or an assembly reference?) and I just cant find a way to solve this..I have added the references.
We have an ASP.NET 2.0 site in which we use ASP.NET login / authentication controls.
Our users currently timeout after approx 20 minutes, forcing them to log back in, and this appears to be causing downstream errors in our application.
I have tried increasing the SessionTimeout value to 120 mins (<sessionState timeout="120" />) in the site's web.config file, and the "<membership userIsOnlineTimeWindow="5000" >" value in the web.config is set to 5000 minutes.
These are the only values / settings I can think of to affect this behaviour.
I am trying out ASP.NET MVC2. I have a controller called SearchController and a view folder called Search containing Search.aspx. In my controller I have:
It works fine the first time I click the button, and the browser shows a url of [URL]. However, when I click the button a second time the browser url changes to [URL] and I get a 404. What am I doing wrong?
am having an argument at work on the asp.net membership provider.One of my colleagues says we should modify the tables and add our own custom columns, and i prefer we create additional tables and add relationships.
1) Extend the CreateUserWizard control to insert additional User fields (eg. Gender, Age, Occupation, Address, Phone, etc...).
OR
2) Create a brand new Custom Membership Provider of my own and skip using the inbuilt ASP.NET membership system.
What is the best way to create a new User system with my own tables of User data as described above?
Should i perhaps still use the standard ASP.NET membership system and then extend my own Registration page to add more User data to my own SQL backend table using the Identity value inserted into the aspnet_users table?

Has anyone extended the Range attribute to be able to have a variable range?I have a similar need but I can't make this work:
public class YearRangeAttribute : RangeAttribute { public YearRangeAttribute() : base(typeof(DateTime), DateTime.Now.AddYears(-100).Year.ToString(), DateTime.Now.AddYears(-14).Year.ToString()) { } }
There is nothing on the page when it is rendered to the browser and the code above doesn't work.
A user who is browsing the site in french experiences no problems UNTIL they walk away from the site for 20 minutes. The site then defaults to english.
I am assuming - based on what I have seen with IIS and Application Pools - that the sites session variable is expiring OR the application pool is recycling. I have changed their limits to 600 minutes (which is 10 hours) and on a test server this appears to work perfectly fine.
On the live server, however, it does not work.
I have edited the <sessionState> variable on the web.config file to also timeout after 600 minutes, and this still doesn't help.
Is there something I am missing? Is there a way to programatically force the session state to not expire for 600 minutes? If there is, could someone provide a sample code snippet as I am a newbie to ASP.Net prgramming. I am using VB for my pages.
