I'm creating a table in an asp.net code behind dynamically, and I want to have a footer row that only has 2 cells. The first should span all the columns in the table-1. Is there some way other then keeping track of the # of columns in the table manually for me to set the colspan to be # of all the columns in the table-1? Preferably a HTML or CSS solution?

Sep 9, 2010

I try to work with MYSql (because it's free) and I saw that the colums are different then when they are exployed in MS SQL?

Why is this? The most strange differents is that in MySQL there is no applicationId in the membership table.

This differents in tables cost me more time to do a export and import from MS SQL to MySQL.

C# - Dynamically Adding Columns To A Table In An MVC View

Apr 20, 2010

I am returning an IList to my model of data about users. I want my end users to be able to select which columns they want to see.

I know I can do this with a huge "if statement" however, I know there must be a better way. I have created an Enum with the column names. I feel if I could take the IListItem.EnumName I would be set. However, I'm not too sure on how to do this.

Here is how I access the table. using user. gives me all columns, but the one I created.

string userName = User.Identity.Name;
MembershipUser user = (MembershipUser)System.Web.Security.Membership.GetUser(userName).ProviderUserKey;

Setting Indexed Columns On A Custom SQL Table

Jul 22, 2010

I've read about primary, unique, clustered indexes etc. But I need to understand it via an example.

The image below is the auto-generated aspnet_Users table captured from SQL Server Web Admin Panel.

Taking this as a model; I will create a custom table called Companies and let's say the fields are: ID, Name, ShortName, Address, City, Country.. No values can be duplicate for ID, Name and ShortName fields.

What is your approach on creating indexes for this table? Which should be clustered or non-clustered? Are indexes below logical to you?

Index Columns Primary Unique Clustered ign.Dup.Keys Unique Key
------------------------------------------------------------------------------------------
PK_ID ID True True False False False
Comp_Index Name,ShortName False True True False False

ADO.NET :: How To Execute Alter Table For Multiple Columns

Oct 24, 2010

I have an SQL table called tbl, im trying to add the columns A, B and C to it.

When i execute the command :

addcolumns = "ALTER TABLE SqlCreatedTbl ADD A char(50) ;";
cmd = new SqlCommand(addcolumns, conn);
conn.Open(); cmd.ExecuteNonQuery();

The column is added perfectly and i can see it in the table !

However, when i try to add multiple columns, it does NOT work, it gives me an error..

the command im writting for adding multiple columns is the following:

addcolumns = "ALTER TABLE SqlCreatedTbl ADD ( A char(50), B char(50), C char(50) );";

the debugger highlights the line : cmd.ExecuteNonQuery(); and throws the following exception: Exception Details: System.Data.SqlClient.SqlException: Incorrect syntax near '('.

MVC :: Scaffolding And Hiding Table Columns In The View?

In the controller:

[Code]....

Shouldn't ScaffoldColumn(false) hide the field in the view? I create a strongly typed CREATE view (AddSO), expecting that the soID column won't be rendered and that the Label name of the field 'name' will be 'Full Name'. But the AddSO view renders the soID column and still labels the 'Name' field as 'Name. What am I doing wrong?

Web Forms :: Spread A Radiobuttonlist Across Several Columns In A Table?

Sep 22, 2010

Probably an odd question, but I'd like to know if it's possible to have a table with 3 columns and have a radiobuttonlist that spans these 3 columns with 1 radio button per column?Perhaps there's a more sensible way to do this, I've got 3 options that I'm going to pull from a database to populate the radiobutton list with and I want to repeat it "x" times.So imagine a questionnaire with 10 questions, and your only answers to each question are yes, no or maybe, I want something like all of the yes radio buttons in the first column, "maybe's" in the second column and "no's" in the third column (Just to make it look pretty).I know that I could manually put 3 radio buttons in a row, 1 per column, and give them their own ids etc, but that's working hard, not smart :)

Databases :: Defining Index On Table Columns?

Mar 5, 2011

On one of our tables, a default clustered index is defined on the primary key by sql server 2005. The table also contains forign key columns and has got over 2 million rows. There are very frequent INSERT, UPDATE and DELETE functions on this table. Recently some of the SELECT queries which primary operate on the forign keys have become very slow (resulting in application timeout). To fix the problem, I defined an index on one of the primary keys which gave me very quick results. I don't know much about indexes.

1. Since I defined a new index (on the forign key) in addition to the existing default index, what kind of index (clustered or non-clustered) have I defined?

2. What performance impact does it have on the rest of the system? Is it going to break something else?

3. I read about fill factor. What is this and how does it effect the system?

4. Is the new index physically going to make any changes?

5. In case I delete this index later on, will the database return to the existing state or it will be a different state from now?
