C# – Splitting CamelCase

asp.netcstring

This is all asp.net c#.

I have an enum

public enum ControlSelectionType 
{
    NotApplicable = 1,
    SingleSelectRadioButtons = 2,
    SingleSelectDropDownList = 3,
    MultiSelectCheckBox = 4,
    MultiSelectListBox = 5
}

The numerical value of this is stored in my database. I display this value in a datagrid.

<asp:boundcolumn datafield="ControlSelectionTypeId" headertext="Control Type"></asp:boundcolumn>

The ID means nothing to a user so I have changed the boundcolumn to a template column with the following.

<asp:TemplateColumn>
    <ItemTemplate>
        <%# Enum.Parse(typeof(ControlSelectionType), DataBinder.Eval(Container.DataItem, "ControlSelectionTypeId").ToString()).ToString()%>
    </ItemTemplate>
</asp:TemplateColumn>

This is a lot better… However, it would be great if there was a simple function I can put around the Enum to split it by Camel case so that the words wrap nicely in the datagrid.

Note: I am fully aware that there are better ways of doing all this. This screen is purely used internally and I just want a quick hack in place to display it a little better.

I used:

    public static string SplitCamelCase(string input)
    {
        return System.Text.RegularExpressions.Regex.Replace(input, "([A-Z])", " $1", System.Text.RegularExpressions.RegexOptions.Compiled).Trim();
    }

Taken from http://weblogs.asp.net/jgalloway/archive/2005/09/27/426087.aspx

vb.net:

Public Shared Function SplitCamelCase(ByVal input As String) As String
    Return System.Text.RegularExpressions.Regex.Replace(input, "([A-Z])", " $1", System.Text.RegularExpressions.RegexOptions.Compiled).Trim()
End Function
