C# - Parseable MVC Razor Syntax

Sep 15, 2010

Here is what I would like to express by Razor:

<b>@parameterMapping.Title</b> (Category: @parameterMapping.Category.Title, Regexp: @parameterMapping.Regexp)

But to make it parseable I have to write it this way:

Are there better ways to solve this problem?

Textbox - Validate Text Box Contains Integer Greater Than Equal To Zero?

Mar 29, 2010

If I want to validate that a text box contains an integer greater than or equal to zero. Do I need to use TWO asp:CompareValidator controls: one with a DataTypeCheck operator and one with a GreaterThanEqual operator?

Or is the datatype operator redundant? Can I just use a single validator with the GreaterThanEqual operator (and the type set to Integer)?

Mar 17, 2010

I have a check box list with some items. I want to make it a single selection. A Radio button list won't work because I need it to allow no selection.

Javascript - How To Check Whether A Certain Text Box Exists In A Page

Feb 9, 2010

Suppose I have a master page where I have written some javascript to access the value of a particular asp.net text box, which resides in one of its content pages, but not in all the pages. This piece of javascript code can't be moved to that particular content page because of some restrictions.

Now I need a way to determine whether or not that text box exists in the page, which will imply that the content page containing that text box has been loaded.

How I can I do that in javascript?

C# - Check Text For HTML With Regular Expression?

Nov 23, 2010

This is slightly different to most questions regarding HTML tags in strings - I want to add HTML!

I'm using a WYSIWYG editor which produces some eratic results. What im looking to do is to check the string it produces and check whether there are any sentences that aren't wrapped in a <p></p> tag. Typical strings could be:

Example 1

<p>Hello, this is string 1</p>

But string two doesnt appear to be in a <p> tag.

Example 2

None of this text is in <p> tags.

Example 3

Single line of text, again not in a <p> tag.

Could this be done using a regular expression?

C# - XElement.ToString() Causes System.OutOfMemoryException?

Nov 25, 2010

I have an XElement object that contains about 120MB of data. The XML consists of approx 6000 elements of about 20kb each.

I am trying to call XElement.ToString() as I need to return the OuterXml in a webservice.

I am getting a System.OutOfMemoryException.

System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown:

at System.String.GetStringForStringBuilder(String value, Int32 startIndex, Int32 length, Int32 capacity)
at System.Text.StringBuilder.GetNewString(String currentString, Int32 requiredLength)
at System.Text.StringBuilder.Append(Char[] value, Int32 startIndex, Int32 charCount)
at System.IO.StringWriter.Write(Char[] buffer, Int32 index, Int32 count)
at System.Xml.XmlEncodedRawTextWriter.FlushBuffer()
at System.Xml.XmlEncodedRawTextWriter.WriteAttributeTextBlock(Char* pSrc, Char* pSrcEnd)
at System.Xml.XmlEncodedRawTextWriter.WriteString(String text)
at System.Xml.XmlEncodedRawTextWriterIndent.WriteString(String text)
at System.Xml.XmlWellFormedWriter.WriteString(String text)
at System.Xml.XmlWriter.WriteAttributeString(String prefix, String localName, String ns, String value)
at System.Xml.Linq.ElementWriter.WriteStartElement(XElement e)
at System.Xml.Linq.ElementWriter.WriteElement(XElement e)
at System.Xml.Linq.XElement.WriteTo(XmlWriter writer)
at System.Xml.Linq.XNode.GetXmlString(SaveOptions o)
at System.Xml.Linq.XNode.ToString()

I have the same data in an XmlDocument and can call XmlDocument.OuterXml without a problem. I can also call XElement.Save() to save the XML to a file without a problem.
