Design A Webform For Entering/editing User Input Using C# Code?
Jul 15, 2010
After going through few asp.net 2.0 books surfacially, I want to accomplish most of the task using c# code and Sql database.
1.we can access and update data using various ways like using sqldatasource code, data reader,command object,dataset,datatable etc.But which one to use in which situation?I am very confused.what do you prefer most,why?
2. How to code professional way? I mean how to separate code using different classes and how to link all togerther?
3.I want to design a webform for entering/editing user input using c# code and use presentation control like gridview and detailsview for viewing,paging and sorting only.Is this possible?
I'm a total newbie with MVC -- learning it with MVC3 using Razor.
I just watched the video on PluralSight and was just following along with the example. I created my own Movie and MovieRepository objects. I then created a strongly typed view for adding a new movie. This is what's in the view:
My Movie object looks like this:
If I click submit without entering anything in the input field, I get validation messages i.e. The Rating field is required or if I enter non-numeric data, I get The field Rating must be a number.
I didn't wire this and wanted to understand where this is coming from.
I am using a server control on a single web.forms page. I have to use this control on a web.forms page since its a server control, although this is actually a MVC project. So I created a web.forms folder and put my new page in it. I then copy the example code from the signature control. I get the following error:
The base class includes the field 'ctrlSign', but its type (WebSignatureCapture.SignatureControl) is not compatible with the type of control (ASP.signaturecapture_signaturecontrol_ctlsignature_ascx).
I know the code works because if I removed the ID attribute from the server control, it no longer gives me this error and my control renders. But I need the attribute for the ID so I can perform is post event
I am using this signature control. Here's the web.forms code...
I have a CMS page that allows the user to paste in or type HTML code into a TextBox in a FormView, then do an INSERT or UPDATE operation to an nvarchar(MAX) column in an SQL table. This is using an ObjectDataSource that refers to an insert or update method in a TableAdapter in my dataset.
When testing, the server initially warned me when I tried to input or update text containing HTML code; so I set the validateRequest="false" in my page header.
I gather this can be a serious security risk. What's the proper way to "validate" the string being input? Am I opening the database to SQL injection?
Only the site administrator has access to the CMS, but malicious could theoretically bust their way in...
I am looking for a tutorial or more information on creating a Templating system to allow a user to edit the template of a ASP.Net website, Such as creating his or her own 'Skin'.point me in the right direction.
Iīm creating a user page to enable editing their profiles. When hitting the "update" button, it turns out that the field still contains the old value, although youīre looking at the new one, ie the text property of the textbox isnīt the value of the parameter which in fact gets its value from the text property.As far as I know I havenīt done anything I havenīt done before, both in apps and website?
I would like to program an Input Box that comes up when a user clicks 'Find' button. It asks 'Please enter an employee number'. Then it takes the employee number typed into a text box and searches a dataset for that specific employee record.
I need expression for following things1.HH:MM in Military format2.mm/dd/YYYYThere is one catch if user is not entering any thing system should not show any message but if he is entering any thing then it should ask from the format.I am using a grid view with 20 rows ans in that so many columns are available. In that grid i have to check this thing
how to restrict the other user if one works on the particular record.
i am having a table with the name tblProduct and i used to edit the records from the code behind using my website.
When one user login into the site andÂ search for the particular products and edits the product and at the same time other user log in and try to edit the same product, i need to show the alert message, "the user (username) is already working on this. please wait for a while."
i was wondering if anyone could help me with a problem i have. im not sure how to go about this exactly i have a web site for a group of ramblers
i have a master/details page which shows walks planned for the future and they can click "details" for the full details
but what i want to incorporate into it is that when they are looking at the full details there is an option to add them to it as attending by entering a user name and password (saved in a table in the database) and if entered correctly their username will be added to it as attending.
I wanted to know how to add the feature- that user should be redirected to an error page where the error will be display, upon entery wrong username/password when trying to login through an asp.net login control?
1. how to redirect the user to an error page upon entering wrong username/password (from a login control which is placed on master page)?
2. how to pass the error to the error page so it can be displayed there?
I am struggling to login into my web portal on my new sony vaio laptop. I think that I need to do some settings, or download some plugin. Infact I don't know what to do, as I have spent many hours trying to login, but no success. Below is my office website:[URL]When I enter my credentials and click login, the web page gets refreshed, i.e username and password get erased, rather than taking me into my web-portal. The laptop is having windows 7 home premium, with ie8. I have also tried installing firefox, chrome, opera and safari, but same problem.
as sony has refused to take the laptop back and they are saying that there is problem with website. Similarly, website staff are saying that there is a problem with the laptop and not with the website.
