Is it possible to add a property to the existing asp:BoundField control without creating a brand new instance to which I'd have to declare <tst:BoundField></tst:BoundField>? If so, can someone provide an example?
View 1 RepliesI want to know if it is possible to extend the properties of a button and possibly override the render() method?I know how to create a custom server control and that is not what I want to do.I have a lot of web application that need to inject some java script on the button render event based on a new properties value.So what I want to do is extend the properties and hook into the Render method of the button control that ships with .net, I want to do it this way then I can still use the default button control but am able to effect all of the buttons in all of the web applications by simply re-publishing them.Inheriting from the System.Web.UI.WebControls.Button class enables me to add the property but then I have to register the "new" control and I have to go and change all of the buttons in all of the web applications.
View 3 RepliesI would like to outsource pieces of a new web application/site. I don't want one company working on the whole project because they can easily change a few things and sell the software to someone else. I will be using a freelenace website like elance or guru. A buddy of mine has given me this advice but he did not say how this can be done.
View 2 RepliesI am trying to comprehend what I need to accomplish but I'm even struggling with the logistics of a this task. Okay, so I am pulling in a field from a SQL table. An example string value would be "Text: 150". The string for this field will always start with "Text:". I need to take the value, strip the "Text:" off the value, then compare the number at the end to carry out further error checking. Hopefully that makes some sense. I've never tried to do anything like this so I don't even know if it is possible.
View 5 RepliesThis obviously isn't right but I think best describes what I'm trying to do:
SELECT ImagesLge.MainImages
FROM pieces
INNER JOIN ImagesLge
ON ImagesLge.ParentId = pieces.ID
"WHERE pieces.ID = MAX(pieces.ID)"
I'm trying to do: I have a webform with a datalist. The datalist shows projects (projectname, image and an imagebutton). When a visitor clicks the imagebutton two events should take place:
- First: data should be send to SQLdatabase (projectID, name of project, sessionID, datetime etc).
- Second: a pop up window must be opened to an existing webpage of the facilitator of the project, using an url which (is in my database).
The problem is my two seperate pieces of code-behind work fine, it's just that they won't work together. Here is my code: The imagebutton:
< asp:ImageButton ID="openButton" CssClass="openbutton" runat="server" ImageUrl="~/Images/openButton.png" CommandName="Sendto" CommandArgument='<%#Eval("ProjectID")%>' OnDataBinding="openButton_DataBinding" ></asp:ImageButton>
Code behind send to database:
protected void list_ItemCommand(object sender, DataListCommandEventArgs e)
{
if (e.CommandName.ToString() == "Sendto")
{
string projectId = e.CommandArgument.ToString();
bool succes = ProjectAccess.Projectopen(projectId);
}

I work in a web agency and thus we are plenty of websites from several customers. They're built upon a cms we made, so websites are quite identical for the 90% of code. However, remaining 10% struggles me and my team as it involves not only the presentation layer but behavioral logics too (ex: a website1 requires simply user/pass registration while website2 needs more data, facebook connector, etc. But this is a very easy example). Making ad hoc development for our customers is becoming painful as keep each version aligned is getting really hard for us What I really dream to have is an extendible website that works by itself, but in which I can override a part. This behavior should sound like "look for the specific part, if it doesn't exists get the base one". The parts could be a method, a class, a page, a control, a static file.
example:
Suppose I want website2 to have an own login component, let's so imagine that we have a situation like:
/website_base
|_ login.aspx
/website1
/website2
|_ login.aspx
So, if I ask for [URL] I'll get /website_base/login.aspx, but if I ask for [URL] I'll get /website2/login.aspx

i want override method Hello() above in Web User Controls

I'm not talking about asp.net membership.
For each logged user I want to cache some properties like status or the number of friend requests, from the db.
I can create custom class which would do it but I thought it will be better to extend the existing User.Identity property. Something like this:
Label1.Text = User.Identity.Status;
How to extend a compareValidator so i can check, if user has written some text in ControlToValidate then he must write some text in ControlToCompare too.
View 1 RepliesWe are using entity framework and we have two projects with two different edmx files. We need to keep both tables in same database and we want to extend funtionalities of one project by the other one. Is there a way to extend edmx files or is there a better solution for this?
we have 3 edmx files in three class libraries.
1.person class library(Core) with core.edmx-Basic details related to a person(name,email ...)
2.CV Claas library with CV.edmx wich have CV related data(Experiance,skills... )
3.Customer Relationship management system(CRM) which have customer data(sales data...)
Then we want to use core class library edmx file(Core.edmx) with cv.edmx (basically cv tables should be able to use tables from core tables) . Same way we want to use the core.edmx with CRM.edmx for the 3 rd project

I have noticed how editing the web.config file in an application folder causes that application pool to recycle and pick up the changes.
How does IIS achieve this and is it possible to extend this functionality for another config file? Or is this dependency hard-coded somewhere? This is related to the possiblity of deploying configuration changes to a web server without having to edit the web.config, which is usually maintained by a different team.
Note that I don't want to manually invoke this recycle event, but have it work in the same way as with web.config. I'm aware that I could simply add these settings to web.config, but that's not what I've been asked to do.
I have a handler, like this, using IRequiresSessionState:
public class MyHandler : IHttpHandler, IRequiresSessionState
{
// code
}
In the code, I am able to read and set Session values. I also check ensure that the caller is logged in. That all works fine.
The web site uses forms authentication, so in the web.config, I have this:
<authentication mode="Forms">
<forms loginUrl="Login.aspx" timeout="10" slidingExpiration="true"></forms>
</authentication>
The problem is that AJAX calls from the client to the server code MyHandler do not extend the life of the session!
So even if the user is busy sending and receiving data from the server, they time out 10 minutes after their last full page load.
In the handler, I've tried specifically changing a value is the session on each call, but not even that extends the time out.

I am obviously missing something here and it is driving me batty. I am trying to implement a custom role provider so that I can add some of my own custom code to it. I have created my CustomRoleProvider class, I have inherited the RoleProvider base class and implemented its members. I have made the required changes to my web.config so that my CustomRoleProvider is used. This is all working great.
All of this is wrapped up in a wrapper class as provided by the MVC Membership Starter Kit that I am using and wish to extend.
Now I want to add my own custom functionality.
When I add a function to my CustomRoleProvider I cannot see it or access it.
How do I add functionality to my CustomRoleProvider so that I can use it?
I'm trying to extend the requirefieldvalidator to take a new property and validate regularexpressions also. I know I can use the RegularExpression control but then i need 2 controls so i want to eliminate it so i only have to use two controls. There are also other features i want to make which include me extending it. My problem is i don't know what to override - i tried the Validate() but i get "cannot override inherited member 'System.Web.UI.WebControls.BaseValidator.Validate()' because it is not marked virtual, abstract, or override" and i understand the EvaluateIsValid() is for validating the control not what is in the control.

I am busy writing my own custom attribute for my action method called MyAuthorizeAttribute, I am still busy writing the code, here is my partial code:
[AttributeUsage(AttributeTargets.Method, AllowMultiple = false)]
public class MyAuthorizeAttribute : AuthorizeAttribute
{
public new Role Roles;
public override void OnAuthorization(AuthorizationContext filterContext)
{
base.OnAuthorization(filterContext);
if (Roles != 0) // Did it this way to see what the value of Roles was
return;
// Here I am going to get a list of user roles
// I'm doing my own database calls
filterContext.Result = new HttpUnauthorizedResult();
}
}
Here is my Role enum:
public enum Role
{
Administrator = 1,
SuperAdministrator = 2
}
My action method:
[MyAuthorize(Roles = Role.Administrator|Role.SuperAdministrator)]
public ActionResult Create()
{
return View();
}
The reason why I did not use Roles = "Administrator,SuperAdministrator" was because the roles are hard-coded. I don't want to have a 100 places to change if the role name changes.
Given my method, when it gets to if (Roles != 0) then Roles total value is 3, how would I check to see if these 2 roles is in the list of user roles for a specific user?
Am I doing it correct here? If not how would I otherwise implement this? It doesn't have to be the way that I did it in.
I need to write some dynamic queries for a project I'm working on. I'm finding out that a significant amount of time is being spent by my program on the Count and First methods, so I started to change to .Single, only to find out that there is no such method.
The code below was my first attempt at creating one (mostly copied from the Where method), but it's not working.
public static object Single(this IQueryable source, string predicate, params object[] values)
{
if (source == null) throw new ArgumentNullException("source");
if (predicate == null) throw new ArgumentNullException("predicate");
LambdaExpression lambda = DynamicExpression.ParseLambda(source.ElementType, typeof(bool), predicate, values);
return source.Provider.CreateQuery(
Expression.Call(
typeof(Queryable), "Single",
new Type[] { source.ElementType },
source.Expression, Expression.Quote(lambda)));
}
I'm trying to style my menu and menu items so it looks like a tabbed menu. I've seen really nice css code examples which I want to use in my master pages. Problem is, when you click @ a menu item, the active menu item should have a other css class than the other ones in order to style them. How can I do this? Is there a tabmenu available which is easy to style and detects when a menu item is clicked?
