I am creating some simple asp.net web forms. All these forms need to have is a simple message that indicates the system is unavailable. Obviously I can hard code this text in the page but it would be nice if I could make the message in one place and all the pages can pull it. Someone just got me looking at resource files, but I need to have this message without having any code in code behind of these pages.
View 2 RepliesI am trying to create a simple menu system using repeaters. In the system I want to use a different formatting for class sub items and am trying to use an If that checks the DataBinders results and branches if its "Classes" but when I compile the code is says:
Name "Container" not declared.
On all the tutorials online and MSDN the Container.DataItem is just assumed to work so i can't find any information on it not working. Can anyone who uses databinders more than me explain this?

I've just rebuilt my PC and have upgraded to visual web developer express 2010. I have imported my projects which use the charting control quite a bit. Unfortunately my projects are failing to run. In design view the control is now showing as "unknown server tag asp:chart". I can see the Chart control in the data tab in the toolbox but it is greyed out.
View 1 RepliesI want to do is create a simple page which allows a user to post data into a data table. It should not allow them to view, update or delete any data.

I'm looking for a simple way of developing "System Notification" in an ASP.NET website, which will consist of two parts: Part 1 - The administrator with go to a special page and enter 3 elements for the notification:
Notification Text (e.g. "System will be down for maintenance next Sunday 11/26/2010 from 1:00 AM to 1:30 AM Pacific Time) Starting date/time when the notification should be displayed (e.g. 11/23/2010 6:00 AM) Ending date/time when the notification should be displayed (e.g. 11/26/2010 1:30 AM) Part 2 - Once the user logs into the website within the above timeframe, the system notification message will appear on the home page. What would be a good architectural location for this?
- A table?
- An html page?
- Part of web.config file?
- A new notification.config file?
- Where else?
I would like to create a secure login page for a pre-defined set of users (so no creating username/passwords by the users themselves). I've looked up a few sites and they all seem to using Microsoft's Membership or something. I am not very sure as to why that's used, but all you need to know is that I will be creating the login details. I just need to make the login secure, ie, no duplicate logins, no logins from different browsers and cookies and sessions and encryption and all that.

View 5 RepliesI want to create a new module in DNN (VB) ... that;
1. does not use DAL or DAL+
2. has only one view.ascx control
3. It has to be a compiled module
I do not need DB connectivity and any bells and whistles just one view control. I thought it would be simple but googling for a day now and it seems very complicated.
I have the development environment already set up with;
1. DNN Starter kit
2. VS 2008
3. SQL server
4. DNN up and running in IIS
5. the project builds successfully
If anyone knows a way I can build a module using the DNN Dynamic Module Template in VS 2008 and then strip off the DAL and all the unnecessary layers and extra controls until I have only a working view.ascx that just prints out "Hello World!" to the screen ...

View 2 RepliesVery new to ASP.NET and C# (somewhat knowledgable in PHP) I have an ASP.NET web application and need to manage access to pages based on a 'status' stored in a cookie. I would like to use the following code to create the cookie in a login method.
HttpCookie cookie = new HttpCookie("UserCookie");
cookie.Value = "status"; <-- this will be replaced with a variable once its working
cookie.Expires = DateTime.Now.AddHours(1);
Response.SetCookie(cookie);
My problem is that the only place I can put this code where it works is in the global.asax Session_Start method. It simply doesn't work anywhere else. I am checking the cookie creation in firefox options and see the ASP.NET_SessionId created but nothing else (This is all running on localhost).
Is the session status somehow interfering with the cookie creation? Do I need to configure something in Web.config? It would appear that the only time I can create a cookie is on Session_Start. Does anyone have any tips, perhaps I am missing something simple?
I want to create ASP.NET like calendar control in .NET (C#)
I want just to simulate like basic calendar control (not AJAX like )which shows dates and traverse the months.
Rather than try to reinvent the wheel, how to create a stacked/segmented bar or point me to an existing control. Here's what I need:
Horizontal bar
Standard html
Each segment needs to be color coded from css
Each segment needs to be a percentage of the total (i.e. if total value = 100, then a value of 10 for one of the segments would be smaller than a value of 50)
Should be able to fit seamlessly into an html table cell
Should not be an image
Should only create a single bar with segments (not multiple bars/segmented bars)
Server-side generated, no AJAX
This should be as simple as possible given x number of values, create x segments.
I'm looking for code examples or already-built controls.
EDIT: For completeness:
int[] segments = { 10, 5, 45, 20, 20 };
Panel horizontalBar = new Panel();
for(int segmentIndex = 0; segmentIndex < segments.Length; ++ segmentIndex)
{
horizontalBar.Controls.Add(new Panel() { ID = String.Format("segment-{0}", segmentIndex), Width = Unit.Percentage(segments[segmentIndex]), CssClass = "segment" });
}
this.Page.Form.Controls.Add(horizontalBar);
I am looking for a simple (or best practice) way of pre filling some of the fields in a create form. As an example, say the create view is loaded for a model that has a datetime field. I want the textbox for that field to be filled with DateTime.Now. I don't need a javascript watermark or anything like that, I jsut want to pre fill the text box.
The GET version of my Create method in the controller just returns the view with no model so I am not sure where to set this value.I've beel trying to figure this out for a while and I must be missing something, I expected this to be really easy.
