ASP.NET (C#) Question

Splitting CamelCase

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.

Answer

Indeed a regex/replace is the way to go as described in the other answer, however this might also be of use to you if you wanted to go a different direction

    using System.ComponentModel;
    using System.Reflection;

...

    public static string GetDescription(System.Enum value)
    {
        FieldInfo fi = value.GetType().GetField(value.ToString());
        DescriptionAttribute[] attributes = (DescriptionAttribute[])fi.GetCustomAttributes(typeof(DescriptionAttribute), false);
        if (attributes.Length > 0)
            return attributes[0].Description;
        else
            return value.ToString();
    }

this will allow you define your Enums as

public enum ControlSelectionType 
{
    [Description("Not Applicable")]
    NotApplicable = 1,
    [Description("Single Select Radio Buttons")]
    SingleSelectRadioButtons = 2,
    [Description("Completely Different Display Text")]
    SingleSelectDropDownList = 3,
}
