We all know ho to to in html :
<ul>
<li>Coffee</li>
<li>Tea</li>
<li>Milk</li>
</ul>

am creating dynamic rows in a table from List<Productos> but this list have repeats same objects depending of quantity for one product.
[Code]....
I like that the products are not repeated but instead that show the quantity in a label.
String is immutable and StringBuilder is mutable. So if I change the value of a string a new memory created with the new value, whereas in StringBuilder it updates its memory location rather than creating a new memory location. So for large concatenation stringBuilders are preffered. But when I create a new String object, a fixed memory is created. And any changes will update its memory location, rather than creating a new memory location.
For e.g.
String s = new String();
s = String.Empty;
for ( int i=0;i<100; i++)
{
//s = s + "test" + i.ToString();
s =string.Concat(s, "test" + i.ToString()); ///This is effecient compared to previous step
}
Now instead of String class I will use a StringBuilder class.
StringBuilder s = new StringBuilder(String.Empty);
for ( int i=0;i<100; i++)
{
//s = s + "test" + i.ToString();
s.append( "test" + i.ToString());
}

var names = "Brian,Joe,Chris";

i would like to add a search module in my web application. I would like to use drop down list. I would like to know how to connect more than one drop down list in the same page to produce a result.
Example :
Holiday Type : Honeymoon,shopping (select in a drop down list)
Budget : 300-400, 400-500, 500-600 (select in a drop down list)
Result : a suggested holiday pakage (from database).

When exporting a lot of data to a string (csv format), I get a OutOfMemoryException. What's the best way to tackle this? The string is returned to a Flex Application.What I'd do is export the csv to the server disk and give back an url to Flex. Like this, I can flush the stream writing to the disk.Update:String is build with a StringBuilder:
StringBuilder stringbuilder = new StringBuilder();
string delimiter = ";";
bool showUserData = true;

I know this is kind of simple in my head but the logic has been driving me nuts going through it. I'm trying to build a string from 2 list boxes. Once they select an item in the first list box (that's pulling the list items dynamically from a database), then the second list box appears. Once they select the second list box the video player below it displays a flash video that they chose based on which camera and the date/time of that particular camera. The path for the flash video (.flv) is in the database. I get everything to work up to displaying the flv player but it doesn't play the video since the path to the flv isn't there. Here is the code I currently have along with the queries.

I am using Linq To Sql to get List of objects with data from database. To bind data with a grid view i am creating a dataset explicitly and then adding List values to that explicitly created dataset.

View 4 RepliesI have a table that get populated via an external text file. I am not sure of the exact process as I'm relatively new to the company.
The table does not have a primary key as the entire table is dumped and re-loaded every quarter when there is a new text file.
Enter ASP.NET MVC. I need to display that table with checkboxes in a grid so the user can select some rows and send it back to the server. It sounds relatively easy, but I am really not sure what to put as the value for the checkboxes as I am pretty sure I'll need to use multiple columns to create a unique. Yep, I know, I know :).
OldTable
- Field1
- Field2
- Field3
...
- FieldN
The View
...
<input type="checkbox"
name="bunchOfStuff"
value"Field1Value,Field2Value,Field3Value"/>
...
Would something like this work? If I can create a key with a few fields, can I use those fields as the value in the checkbox? I realize my action will be a bit ugly as I'll have to split and parse each value in the array of values.

Split the input string based on the separator list passed. Returned string list should have separators in it.
.NET API needs to be implemented
string [] SplitWithSeparators( string inputText, string[] separators)

inputText: passed string
RAMESH EMPCODE 001 SURESH EMPCODE 002 GIRISH EMPCODE 003
Separators: passed string[]
string [0] : TRINATH
string [1] : SHARATH
