My webGrid is working perfectly fine. However, I would like the default sort order to be in the opposite direction. If it were SQL, I'd be adding a DESC somewhere. Here's my working line of code:
[Code]....
It correctly sorts on the UWDate column, but I would like it to sort the opposite sort order. Of course, once it is displayed, you can click on the title and it will resort at that time.
right now I playing around with WebMatrix and I followed the tutorial from http://www.asp.net/WebMatrix. Chapter 6 (displaying data in a grid) described how to use a WebGrid helper very clear, but the data in the example is always retrieved from an SQL DB.I want to use the same XML file from chapter 7 (Displaying data in a chart).Using the code:
...
var DataSet = new DataSet();
dataSet.ReadXmlSchema(Server.MapPath("/App_Data/QCFiler.xsd"));
[code]...
In the example code, you show how to use the rowId in a hyperlink to a detail page like this:

How do you do this with a WebGrid helper?
Is there a way to format a column with an image?
View 3 RepliesIs there a way to have a calculated column (field) in a webGrid in webMatrix?
View 4 RepliesI've been practicing with WebMatrix and I've come across this problem. I'd like to use the format property of the WebGrid Column in vbhtml but I can't get it to work. I always get some kind of compilation error. Mostly the compiler says that an expression is needed. There must be a crucial difference between the way it's done in cshtml and the way it's done in vbhtml.

View 2 RepliesI am using a Webgrid as part of an MVC 3 app. The weird thing is the first display of the page with the grid displays fine but when I click on a heading to sort, the grid is not displayed as part of the page when I am running under the web server provided by the VS 2010 installation. When I do a View Source of that page, all of the grid stuff (as table elements) is there to be displayed. It just does not show up in the browser. So, I wrote the html to a file and copied the javascript and css files to the same folder and then ran the file under IE and everything displays as it should.

If I have a specific order that I want to sort my List by, how do I do that? For instance, I have a list of items (coming from a database), with ID's ... and they come in order, i.e 1, 2, 3, 4. After receiving this list, I'd like to reorder the list above based on a specific order, e.g. 2, 4, 1, 3. How do I do this without complicate it too much?
View 11 RepliesI have 2 tables with a relationship by EmployeeID (Employee, Cases)
The relationship name is Purchases (ie employee->Purchases), and iterating through it gives each row in order by date (entry order perhaps?).
There could be thousands of rows, so I want to present this collection in reverse date order.
Would I have to define a provider or repository to call instead of just Employee->Purchases?
I am wondering if the aspnet_Users table is always sorted (by UserName) even if I add new users which are alphabetically between two already existing users.
I've noticed that the method Membership.GetAllUsers() always seems to return a sorted collection of MembershipUsers.
Also when I look into SQL Server Management Studio and run a simple SQL query without ORDERBY clause...
SELECT [UserName]
FROM [MyDb].[dbo].[aspnet_Users]
...I get always a sorted result list.
I'm still very unfamiliar with SQL Server but I expected that when I add a new row to a table it is (physically) appended to the end of the table. And when I run a select statement without ORDERBY the rows will be selected in the order they were initially inserted into the database (so without any specific sort order).
I am wrong I guess. But how does it really work? Is it perhaps something special with the aspnet_Users table?
I am happy that the MemberShipUserCollection returned by GetAllUsers() is sorted but is it always guaranteed?
Update
I've just noticed that the database contains a stored procedure called aspnet_Membership_GetAllUsers. This procedure actually contains an ORDER BY clause by UserName. So if this stored procedure is indeed always called when I use Membership.GetAllUsers() in my code (at least if I am using the SqlMembershipProvider) it explains why the collection returned by Membership.GetAllUsers() is sorted by UserName.
Remains the question: Is Membership.GetAllUsers() actually based on this stored procedure?
How do I sort a data table based on a particular column which has integer values in ascending order?
I wrote this:
leadtable.DefaultView.Sort = "Id"
But it doesnt seem to work, it displays fine but when i get try to get the values of the sorted datatable in an array they dont come in an sorted ordere Datatble is defined as:view plaincopy to clipboardprint?
I am trying to correct the sort order of my ASP.NET drop down list.
The problem I have is that I need to select a distinct Serial number and have these numbers organised by DateTime Desc.
However I cannot ORDER BY DateTime if using DISTINCT without selecting the DateTime field in my query.
However if I select DateTime this selects every data value associated with a single Serial number and results in duplications.
The purpose of my page is to display data for ALL Serials, or data associated to one serial. When a new cycle begins (because it is a new production run) the Serial reverts to 1. So I cannot simply organise by serial number either.
When I use the following SQL statement the list box is in the order I require but after a period of time (usually a few hours) the order changes and appears to have no organised structure.

For our website, we have decided we would like to maintain our user passwords as encrypted binary data in our database. We are using ASP.NET 3.5 to host our site and SQL Server Express 2008 for the database, both running on the same server. When a user logs in and submits a username and password, there will need to be some sort of encryption or decryption in order to verify the credentials. To me, it would appear that there are 3 ways to do this:
1)[C# Encyrption] On User creation, perform encryption in the Web App and submit the encrypted password to the database. To verify credentials at Login, perform the same encryption on the submitted password and ensure that it matches the value stored in the database.
2)[SQL Encryption] On User creation, submit the plain-text password to the database and have it perform one of the SQL encryption variants during INSERT. To verify credentials at Login, have the database perform decryption on the password during the SELECT statement, and compare the plain-text submitted password to the one in the database.
3)[Mix] On User creation, submit the plain-text password to the database, and have it perform one of the SQL encryption variants during INSERT. To verify credentials at Login, perform the same encryption algorithm used by SQL on the submitted password ( is this possible? ), and ensure that it matches the value stored in the database.
Does anybody have an opinion as to which of these options is best? Number 1) is the most familiar to me, and would be the easiest to use with LINQ to SQL ( which is our current data model ), so I am leaning towards that. But if there are better options I would love to know about them.
I want to orderby the list. Today date is on the top and then next date and all dates but when today date is passed then it comes on the end of the list. Is there any formal query in linq or some other code is used to achieve this?
