Localizing UI elements

You can localize the UI elements of RadExpressionEditor by using a custom RadGridLocalizationProvider. For more details, please refer to this article.

public class CustomLocalizationProvider : RadGridLocalizationProvider
{
    public override string GetLocalizedString(string id)
    {
        switch (id)
        {
            case RadGridStringId.ExpressionMenuItem: return "Expression";
