Solution For Special Character in TextBox Multiline in Magic Ajax For .net 2.0

Introduction

The Magic Ajax For .Net 2.0 have problem with Special values like (ç,á,à,ã,õ,ô,î…) in Textbox Multiline after of post back where update this characters for Html Code like (ç = ç | ñ = ñ). For solution this problem I updated the file AjaxPanel.cs for convert Html Code to Text.

Using the code

First:

I created a method called ConvertAsciiToText like code below:

protected String ConvertAsciiToText(String pValue)

{

pValue = pValue.Replace("&#32;", " ");

pValue = pValue.Replace("&#33;", "!");

pValue = pValue.Replace("&#34;", "\"");

pValue = pValue.Replace("&#35;", "#");

pValue = pValue.Replace("&#36;", "$");

pValue = pValue.Replace("&#37;", "%");

pValue = pValue.Replace("&#38;", "&");

pValue = pValue.Replace("&#39;", "'");

pValue = pValue.Replace("&#40;", "(");

pValue = pValue.Replace("&#41;", ")");

pValue = pValue.Replace("&#42;", "*");

pValue = pValue.Replace("&#43;", "+");

pValue = pValue.Replace("&#44;", ",");

pValue = pValue.Replace("&#45;", "-");

pValue = pValue.Replace("&#46;", ".");

pValue = pValue.Replace("&#47;", "/");

pValue = pValue.Replace("&#48;", "0");

pValue = pValue.Replace("&#49;", "1");

pValue = pValue.Replace("&#50;", "2");

pValue = pValue.Replace("&#51;", "3");

pValue = pValue.Replace("&#52;", "4");

pValue = pValue.Replace("&#53;", "5");

pValue = pValue.Replace("&#54;", "6");

pValue = pValue.Replace("&#55;", "7");

pValue = pValue.Replace("&#56;", "8");

pValue = pValue.Replace("&#57;", "9");

pValue = pValue.Replace("&#58;", ":");

pValue = pValue.Replace("&#59;", ";");

pValue = pValue.Replace("&#60;", "<");

pValue = pValue.Replace("&#61;", "=");

pValue = pValue.Replace("&#62;", ">");

pValue = pValue.Replace("&#63;", "?");

pValue = pValue.Replace("&#64;", "@");

pValue = pValue.Replace("&#65;", "A");

pValue = pValue.Replace("&#66;", "B");

pValue = pValue.Replace("&#67;", "C");

pValue = pValue.Replace("&#68;", "D");

return pValue;



}

Second

I updated the line 582 in method called ReflectUpdatedFormValues

From

AjaxCallHelper.WriteSetFieldScript(clientID, text);

AjaxCallHelper.WriteSetFieldScript(clientID,ConvertAsciiToText(text));

Third

Compile the project Magic Ajax for .net 2.0.

Conclusion

This update solves the problem for developer’s that work with Special Character like Latin American.

For download source code of the Magic Ajax access the site http://www.magicajax.net.

Update the UI\Controls\AjaxPanel.cs by new UI\Controls\AjaxPanel.cs in source code from Magic Ajax project.

wouldn't it be more efficient just to extract the char codes instead of running all those replacements?

I mean use a StringBuilder like this: (about a hundred times faster than what you have)

                static string FilterForEscapes(string input)
		{
			StringBuilder sb = new StringBuilder();
			
			for(int i = 0; i < input.Length; i++)
			{
				if (input[i] == '&' && input[i + 1] == '#')
				{
					int asciiCode = 0;
					
					// check to see if we have 2 or 3 chars of asciiness
					if ((i + 4) < input.Length &&
					    input[i + 4] == ';' &&
					    Char.IsDigit(input[i + 2]) && 
					    Char.IsDigit(input[i + 3])) // 2 chars
					{
						asciiCode = ((int)(input[i + 2] - '0')) * 10 + ((int)(input[i + 3] - '0'));
						sb.Append((char)asciiCode);
						i += 4; 
					}
					else if ((i + 5) < input.Length &&
					         input[i + 5] == ';' &&
					         Char.IsDigit(input[i + 2]) &&
					         Char.IsDigit(input[i + 3]) &&
					         Char.IsDigit(input[i + 4])) // 3 chars
						
					{
						asciiCode = ((int)(input[i + 2] - '0') * 100 + ((int)(input[i + 3] - '0')) * 10 + ((int)(input[i + 4] - '0')));
						sb.Append((char)asciiCode);
						i += 5;
					}
					else
					{
						sb.Append(input[i]);
					}
							
					
				}
				else
					sb.Append(input[i]);
			
				
			}
			
			return sb.ToString();
		}

Hi Dave, I created this code like a example, Exist other's methods more fast and clean. A good example is this "HttpUtility.HtmlDecode(Text)" posted by José Carlos Chaves de Melo Junior. Your code it's a good example to work with ASCII, why you don't post this code like a article? you it will help many programmers. Tks by Comment in my Article. Leandro Ikezili

Haha that's what I get for not reading all of the commments. I missed the simple HttpUtility.Decode() right there below this one. Anyway, I've been on a lexical analyzer/parser writing kick lately and this just seemed to be one of those problems I could see through in two seconds, so I threw something up there.

Sorry by time to response your question. Well, i don´t tried the update in MagicAjax 1.2, but i think that is equal of MagicAjax 2.0

Code improvement

José Carlos Chaves de Melo Junior

15:47 12 Jun '06

Use this code at line 582: `AjaxCallHelper.WriteSetFieldScript(clientID, HttpUtility.HtmlDecode(text));` This a much more clean code. \|---------------------------\| \|José Carlos C. de M. Junior\| \|Consultor Independente \| \|---------------------------\|

Might be better to make a regex that fetches the character ascii codes from the - ÿ range, since == (char)32;.. would mean a bit more code but will probably run a tad smoother

I saw on the code project another place where someone wrote out this entire code like you did - but there was a one line of code that did the trick for the whole conversion - had something to do with using char to hexvalue instead of hex? - the same applies for ascii .. I think you would be able to write one line or two of code in your application instead of the huge amount you have - if I find that article again!! - you could use for this somewhere here on code project I saw it last night as I was reading another article about encrypting config file key values - it applied to .NET 1.1 - but the code would work also for 2.0
