Hi Naureen,

You can create your own user-defined function where you can apply the logic for converting a string to camel-case or proper-case. For example:

[Function(Category = "My Test Functions", Namespace = "MyTestFunctions", Description = "Return Proper Case String")]
public static string ToProperCase(string text)
{
    var words = text.Split(new[] { ' ' }, StringSplitOptions.RemoveEmptyEntries)
         .Select(word => word.Substring(0, 1).ToUpper() +
                         word.Substring(1).ToLower());

    var result = String.Concat(words);
    return Regex.Replace(result, "(\\B[A-Z])", " $1");
}

How to create and use custom function is explained in User Functions help article.
Note that to use custom functions inside the Standalone Designer it needs to be extended - check Extending Report Designer help article for reference. The designer folder is placed in default Telerik Reporting installation folder, e.g. C:\Program Files (x86)\Progress\Telerik Reporting <VERSION>\Report Designer).
