Using Delegates and Predicates
Posted in C# Programming on May 19th, 2010 by phoenixdigital1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | public new TList<T> FindAll(Predicate<T> match) { if (match == null) { throw new ArgumentNullException("match"); } TList<T> result = new TList<T>(); foreach (T item in this.Items) { if (match(item)) { result.Add(item); } } return result; } |
1 | list.FindAll(delegate(TempAddItem t) { return t.ShortCode.Trim() == 'Test'; }); |
Adding indentation and headings to .NET DropDownList
Posted in C# Programming, VB .Net Programming on April 21st, 2010 by phoenixdigitalI have been able to add indentation to dropdown boxes to allow for easier user viewing in many languages… until I met .NET. For some reason when adding spaces to the text in a ListItem the spaces are magically removed.
I was wanting to acheive a DropDownList like below.
Also at the end of this post is a way to achieve the unselectable headings in the example above.
Number formatting in c#
Posted in C# Programming on April 13th, 2010 by phoenixdigitalA quick simple note on how to add prepending zeros to a number
1 2 | int nMaxNumber = 3; string strValue = string.Format("{0:0000}", nMaxNumber); |
strValue will contain 0003
I will add more examples as I need them

C# Date formatting and Parsing
Posted in C# Programming on March 29th, 2010 by phoenixdigitalHere is a post so I can easily find the correct format for dates
1 2 3 4 5 6 7 8 9 10 11 12 13 | // create date time 2008-03-09 16:05:07.123 DateTime dt = new DateTime(2008, 3, 9, 16, 5, 7, 123); String.Format("{0:y yy yyy yyyy}", dt); // "8 08 008 2008" year String.Format("{0:M MM MMM MMMM}", dt); // "3 03 Mar March" month String.Format("{0:d dd ddd dddd}", dt); // "9 09 Sun Sunday" day String.Format("{0:h hh H HH}", dt); // "4 04 16 16" hour 12/24 String.Format("{0:m mm}", dt); // "5 05" minute String.Format("{0:s ss}", dt); // "7 07" second String.Format("{0:f ff fff ffff}", dt); // "1 12 123 1230" sec.fraction String.Format("{0:F FF FFF FFFF}", dt); // "1 12 123 123" without zeroes String.Format("{0:t tt}", dt); // "P PM" A.M. or P.M. String.Format("{0:z zz zzz}", dt); // "-6 -06 -06:00" time zone |
as well as the way to call TryParseExact
1 2 3 4 5 6 | DateTime completedDateEnd; if (DateTime.TryParseExact(Request["completedDateEnd"], "yyyy-MM-dd", CultureInfo.InvariantCulture, DateTimeStyles.AssumeLocal, out completedDateEnd) { // do stuff } |
also remember to add this to the using statements at the top of the page
1 | using System.Globalization; |

HTTP Post from code behind in C#
Posted in C# Programming on January 21st, 2010 by phoenixdigitalSometimes you may be required to send some data to a remote site from the code behind via HTTP. Generally this can easily be perfomed if the site allows for GET submissions. However sometimes the site will only accept POST submissions.

Style missing from AjaxToolkit Tab Container
Posted in C# Programming, VB .Net Programming on December 1st, 2009 by phoenixdigitalIf you notice the style is missing from your AjaxToolkit Tab Container. It could be due to the fact that when your page first loads this element is not visible either due to a surrounding div not being visible. This may cause the stylesheet for the Tab container not to load on subsequent postbacks when you make the Tab Container visible.
