I was just wondering when it would be appropriate to undertake an object orientated approach when building a dynamic ASP.net website. How is it done? Could a website such as Amazon.com be object oriented? I'm just quite curious as to how it is done, because in any of the simple ASP.net websites I have created, I have never created a "user" class, and then in turn created a "user" object for each new user for example..I have instead just created stored the new user in the database.
I want to write a small shopping cart. I just want to know how can I make use of Object Oriented Programing in it. I want to write ddls for all main classes. for example if I talk about cutomer class or product class how i can write Abstract classes/Interfaces.
I have the following code in my form load that loads the reports and assigns it to crystalreportviewer control. If Not IsPostBack Then
[Code]....
Following is the ApplyCRLogin Class
[Code]....
Now when I run the site it prompts me for the parameters and when I enter them and click on OK, I get the following error. "Object reference not set to an instance of an object." But the strange thing is if I comment the "If Not IsPostBack Then" condition, my report works fine. The problem is even when I want to go to the next page in report, the code get executed again and this takes time. Is there any other way to fix this?
in my default.aspx page i have a dropdown List and a textbox with a submit button below that there are 2 listbox... and the dropdown list holds the names of the listbox
my logic here is to select an item from the dropdown list and put some text in the text box and submit the form which will add an item to the listbox selected.. but when i do this i get an error saying Object reference not set to an instance of an object. i tried to figure out the problem and found that when i remove the reference to the Site Master Page it works fine and when i undo and apply my reference back to the Site Master Page i get the same error.
The error i get seems to be centered around jquery finding what it's in (window,document, etc.). Right now i'm just trying to implement the jQuery datepicker. the project has a master page, where i placed my script references.
I have a <asp: Menu with Orientation="Horizontal" for the StaticMenu.When hovering over the StaticMenu and a DynamicMenu appears, how do I make its orienation horizontal?
I have this table called "students", with the columns :Name, ID, Faculty.
I want to display the info in my .aspx page in such fashion that the columns will appear on the left, the ID on the top, and the data populated properly.
So, basially, should look something like this:
ID 123 234 345 456 567 234 135 135 Name John Erick... Faculty CS BIo ...
setting the Orientation of Viewport.... so that when i change the Iphone in portrait or landscape mode it's contents should also be changed accordingly.
Site developed in VS2010, using Framework 4. I upgraded from a VS 2005, Framework 2.I have a master page with a Navigation Menu set to Horizontal Orientation. When most of the pages on my site are renders, the Nav Menu briefly displays as Vertical before displaying as Horizontal. It ususally takes less than a second, but looks ugly from a user stand point. Anyone else run into (and fix) something like this?
I am using the Chart control unbound and binding data to it at run time. It is a bar chart. When it is displayed after applying the data the X axis is drawn vertically and the y axis is drawn horizontally. I want the opposite but cannot find how to change the orientation.
It seems that when trying to upload(save) an image taken by a mobile device to file, the orientation gets messed up and you end up with images that are rotated 90 degrees to either side. This is an issue I am currently having.
Code: [HttpPost] [ValidateAntiForgeryToken] public ActionResult AvatarEdit(HttpPostedFileBase NewAvatar) { //SAVE TO SERVER string newid = Guid.NewGuid().ToString();
[Code] ....
Would I need to convert originalImage to a file type of HttpPostedFileBase or is there a more elegant way to save the file? I tried reconverting it to a stream and then saving it to file, but I failed miserably.
After uploading image it appears somewhat like its upside getting down. I have getting some other suggestion for that is use ExifLib but I don't know how to get exif detail of image and fix image orientation property if it rotated automatically..!
I have an Entity Framework data model. Part of the model is a Customer entity. The web service provides a method to get a customer, and to receive an updated version of this customer to be persisted.
To test this, I created a new ASP.NET web Application, (Solution > Add > New Project > ASP.NET Web Application), then added a reference to my service reference using the standard Add Service Reference dialog. I then call the service using the following code:
var client = new CustomerServiceClient(); var customer = client.GetCustomerByID(18); // get it customer.LimitDown = 100; // change it client.SaveCustomer(customer); // persist it
Everything works as expected.
Now, I do exactly the same thing, but this time with as ASP.NET Web Site (Solution > Add > New Web Site > ASP.NET Web Site). I add the reference in a similar fashion and copy and paste the code above into the new site. But now I get the following exception thrown on the 4th line:
System.InvalidOperationException The EntityReference object could not be serialized. This type of object cannot be serialized when t RelationshipManager belongs to an entity object that does not implement IEntityWithRelationships.
Source Error:
Line 2474: Line 2475: public SkyWalkerCustomerService.OperationResult SaveCustomer(SkyWalkerCustomerService.Customer[code]....
Googling for this error returns very little. Why doesn't this work?I guess one answer would be to use a web application instead of a web site, but I have an large existing site to which I need to add the service reference, and I'd rather not convert it.
I am exporting a gridview in MS Excel as mentioned in the following link:
[URL]
I want to set orientation of excel pages as landscape. Is there any way to do that? Any header information to be added for file being exported to set orientation of pages as landscape?
Is there a way of detecting the orientation of an image landscape verses portrait or other so that the image is displayed correctly? - What I have is an Ajax HoverMenuExtender with an image contained in a panel. The panel is part of an Ajax Accordion and the image appears in the panel (via a string value for location) when I hover over a thumbnail in the Accordion's Content.
I have a requirement where I have to transfer a user from Web Site 1 on Server A to web Site 2 on Server B.
On Web Site 1, I have to provide controls to enter user id and password and which have to be validated on Web Site 2 on server B, after validating them I have to redirect the user to Web site 2.
what is best way fo doing it. code examples are greatly appreciated.
Note: On Web Site 2, user login functionality is already existing and it is provided by ASP.Net login control, am not sure how to handle the user login process from two different places.
or is it the best way to move Web Site 2 from Server B to Server A so that, the same login controls will be shown using Iframe on Web Site A.
