    {
        decimal decVal;
        double dVal;
        int iVal;

        if (decimal.TryParse(strVal, out decVal))
        {
            range.Value = decVal;
        }
        else if (double.TryParse(strVal, out dVal))
        {
            range.Value = dVal;
        }
        else if (Int32.TryParse(strVal, out iVal))
        {
            range.Value = iVal;
        }
        else
        {
            range.Value = strVal;
        }
    }
    else
    {
        range.Value = null;
    }
}
